The shell allows the DOS user much greater efficiency than the standard DOS interface affords. Typical DOS functions of executing, finding, copying, moving, deleting and listing of files and directories can be done with significantly fewer key strokes when using the Still River Shell; recursive operations produce even greater efficiencies. And the shell provides a natural, intuitive interface which makes using DOS both more fun and more productive. You save a lot of work and time using the Still River Shell through the substantial elimination of command and operand typing. The shell allows you to use directly system information, such as file and directory lists, without having to copy the data from the screen and reenter it on your command line. You can select common commands without typing them. You can recall, edit and reenter DOS commands from the shell's prior DOS command stack. A powerful feature allows you to define your own extensions to the Still River Shell's command set. The Shell's full screen, real time presentation makes it an ideal system interface for mass storage systems such as the IBM/XT and IBM/AT. We could go on about the virtues of the shell, as we did in an earlier version of this document, but the best way to find out about the shell is to use it. The shell is designed to grow on you; you can use the shell productively right away while you learn about its other features. You may find it helpful to follow along during the demonstration session and to review briefly the commands in the reference guide. We hope you like the Still River Shell as much as we do. Remember, it is now your program too! Help support the Shell by sending your comments and contribution (see the INFO command). Thank you for your interest and support. - 4 - Still River Shell Introduction 2.2 Optional Performance Consideration The shell's performance, as well as that of many other programs, is much improved by instructing PC-DOS to keep a pool of IO Buffers numbering 14 or so. These buffers, used by DOS to speed up disk reads, are allocated by PC-DOS at "boot" time either by default or as specified in the CONFIG.SYS file. Either edit an existing CONFIG.SYS file or, if there is none, create a new one. The CONFIG.SYS file should be in the root directory (\). The CONFIG.SYS should read in part: BUFFERS=14 If you prepare that file now, we can BOOT under our new configuration. If you do not wish to do it now, try to remember to do it later. 2.3 Futures For every published work there comes a time when you have to say: "It's done" or at least "Version 1 is done". When, after two years of design and development, that time came for the Still River Shell, some of what we intended was not there. We hope to add, with your support, additional functions in the future. How the Shell develops in the future depends a great deal on the experiences and wishes of you, the shell user and supporter. Suggestions accompanied by contributions will be accorded the attention they deserve! In fact, it is you, the shell user, who will decide if there will be any future releases of the shell. We can not continue our work without your support. 2.4 Note of Caution The Still River Shell is a powerful system utility and you should take care when using it. While the shell has had significant design work to help insure proper operation as well as extensive - 5 - Still River Shell Introduction ALPHA and BETA testing to insure its proper execution, the shell, like all programs, can fail, or a user, like all users, can err. Operation of the shell is at the user's risk. - 6 - Still River Shell Introduction 2.5 Demonstration Session 2.5.1 Set Up Please prepare a diskette with only the Still River Shell (SR.EXE) on it; we will use this diskette as our practice area. Mount the diskette on Drive A. Now, select the system default drive and a directory with at least 25 files, the more the better, as the current default directory. You may do this when you start the shell by specifying: ?>A:SR C:\MYDIR start the shell (A:SR) select system default drive (C:) select system current directory (\MYDIR) - 7 - Still River Shell Demonstration Session 2.5.2 Initial Screen When the shell starts, it presents the initial screen. As you can see, there are three main areas, or windows, on the initial screen: ================================= | | | | | | | | | | | | | SET | DATA | | | | | | | | | | | | | ================================= | COMMAND | ================================= - Set List Window on the left is used to list the selected set of files and directories, <selected_set>. - Data Window on the right contains summary information about the <default_drive>, <selected_directory> and <selected_set> or other context sensitive data. - Command Window at the bottom of the screen is used to select and to enter commands as well as to receive responses and obtain help. 2.5.3 Sample Operations Now that you have the shell started, try the following shell operations: To copy a file from the <selected_set> to the practice diskette, perform the following steps: 1. You select a command by entering the letter, upper or lower case, equal to the upper case letter in the command name. In the case of COPY, <C>. The <selected_command> and the <selected_file> appear on the command input line in the Command Window. 2. Move the file <selector> with the <UP/DOWN CURSOR> keys to the file you wish to copy. Note: that the first operand on - 8 - Still River Shell Demonstration Session the command line changes as you move the <selector>. 3. Enter the <to_file> operand, in this case, <A:> 4. Enter <CR> to execute the command. To copy another file to A:, 1. Move the file <selector> to the file you wish to copy. 2. Enter <CR> to execute the copy. To copy some but not all files with a particular extension, e.a. <.BAT>: 1. Enter <ESC> to return to command selection. 2. Enter <S> to select sort. 3. Enter <E> to sort by extension. 4. Enter <ESC> to return to command selection. 5. Enter <C> to select copy. 6. Move the file <selector> to the first file with the desired extension. 7. Enter <A:> to set <to_file>. 8. Enter <CR> to execute the copy. 9. Move to the file <selector> to the next file to be copied. 10. Enter <CR> to execute the copy. 11. Repeat the last two steps until each file you wish to copy is copied. To edit the command line to copy all files of a specific extension, e.a. <.BAT> 1. Position the command line cursor at the first letter of the <from_file> in the command text. For example: COPY LAST.BAT A: ^ 2. Delete the first part of the filename by entering <DEL> until the <from_file> is deleted up to the period changing <LAST.BAT> to <.BAT>. - 9 - Still River Shell Demonstration Session 3. Enter <*> so the command line reads <COPY *.BAT A:>. 4. Enter <CR> to execute the copy. Note: the copy command places a list of the files copied in the Set List Window. 5. Enter <ESC> to return to command selection. To List a new current directory: 1. Enter <L> to select LIST function. 2. Enter <directory_name>. 3. Enter <CR> to execute the change directory and list all files in the new directory. To enter and execute a PC-DOS command: 1. Enter <X> to select the EXECUTE DOS command presentation. 2. Enter <DIR *.*><CR> to execute command under DOS. 3. Enter <DATE><CR> to execute command under DOS. 4. Respond to DATE with <CR>. To recall your prior DOS commands: 1. Enter the <UP CURSOR> twice. You should see the DATE command and then the DIR command. 2. Move the cursor to the first <*> and delete <*.*> with <DEL>. 3. Replace the deleted operand with the <selected_file> by entering <INS>. 4. Enter <CR> to execute the edited command line. 5. Enter <ESC> to return to command selection. To delete some of the files on a: 1. Enter <L> to select the LIST function. 2. Enter <A:> to select a new DOS default drive to A 3. Enter <CR> to change <default_drive>, list all files on <drive a:>'s current directory. 4. Move the file <selector> to the first file to be deleted. - 10 - Still River Shell Demonstration Session 5. Enter <D> to select the delete command. 6. Enter <CR> to delete the file. 7. Move the file <selector> to the next file you wish to delete. 8. Enter <CR> to delete the file. 9. Enter <ESC> to return to command selection. You are on your way! Try the TREE command next, it gives a nice visual presentation of your directory structure as well as allowing you to MAKE, REMOVE or LIST directories. Try all the commands. Watch out for DELETE and MOVE; they can delete files you may miss. - 11 - Still River Shell Command Summary Chapter 3 Reference Guide: Command Summary The following is a summary of the Still River Shell commands. - 12 - Still River Shell CHDIR 3.1 CHDIR Command CHDIR Function To change the current directory under the shell, use the LIST command or the LIST subcommand of the TREE command. Operand 1 Operation Options - 13 - Still River Shell COPY 3.2 COPY Command COPY <from_file_set> [<to_file_set>] [/Q]<CR> Function The COPY command copies the entire contents of the <from_file> creating a new <to_file>. Operand 1 <from_file_set> Any standard DOS file specification [<drive>:][\][<directory>\][<file_name>]. Operand 2 <to_file_set> Any standard DOS file specification or blank. Operation COPY FILEA FILEB Copies FILEA to FILEB in the current directory. COPY *.ASM \SAVE Copies all files in the current directory with an <.ASM> extension to the <\SAVE> directory. Should there be no more room on the target disk, the copy prompts: ^ insufficient space; retry on new disk? (y/n) If you change the disk and enter <Y>, the COPY will resume copying the <file_set> starting with the complete file that did not fit on the prior media. You may use as many media as you need to complete the <file_set> COPY. If you wish to concatenate files, use the DOS COPY command. 1 Options Option (1) Write on existing files ---------- 1. See the OPTION Command - 14 - Still River Shell COPY Option (3) or </Q> Query on multiple operations. - 15 - Still River Shell DELETE 3.3 DELETE Command DELETE <file_set> [/Q]<CR> Function The DELETE command deletes all files in the <file_set> specification. Operand 1 <file_set> Any standard DOS file specification [<drive>:][\][<directory>\][<file_name>]. Operation DELETE *.ASM Deletes files in the current directory with an <.ASM> extension. When a wild card, <*> or <?>, is used in the file name, the set of deleted files is presented in the Set Window. DELETE <selected_file> Deletes the highlighted, <selected_file> in the current set window. After the <selected_file> is deleted, an adjacent file is selected as the new <selected_file> in both the Set Window and the command line. Options Option (3) or </Q> Query on multiple operations. - 16 - Still River Shell FIND 3.4 FIND Command FIND <file_set><CR> Function The FIND command creates an ordered list (<drive>\<dir>\<file_name>) of all files within the <file_set>. Operand 1 <file_set> Any standard DOS file specification [<drive>:][\][<directory>\][<file_name>]. NOTE: Drive and directories can be specified with a wild card <?> or <*>. Operation FIND FILEA.BAT Lists any FILEA.BAT in any directory on the current drive. FIND C:*.* Finds all files in all directories on disk <C:>. FIND \DIR4\*.bat Finds all <.BAT> files in directory \DIR4. FIND \DIRX\*\*.BAT Finds all <.BAT> files in any subdirectory of the <DIRX> directory. FIND \*\CMD\*.BAT Finds all <.BAT> files in a <CMD> subdirectory of any parent directory. FIND *:*.* Finds all files on all drives from a to z. Options None. - 17 - Still River Shell INFO 3.5 INFO Command INFO Function The INFO command displays license information including our address, suggested contribution, credits and how to order the latest versions of the Still River Shell program and unabridged documentation. Operand 1 None. Operation Strike any key to see next page. Options None. - 18 - Still River Shell LIST 3.6 LIST Command LIST [<drive>:] [<path>] [<file_set>] <CR> Function The LIST command presents an ordered list of files and subdirectories from a <selected_directory> based on the <file_set> specification. In addition, the LIST command can change the system's default drive and current directory to a specified drive or directory. The <selected_directory> always becomes the system current directory when the LIST command executes. Operand 1 <file_set> Any standard DOS file specification [<drive>:][\][<directory>\][<file_name>]. Default: <*.*>. Operation The initial <file_set> list is presented in file name order. If a directory is specified in the <file_set>, the specified directory is listed and it becomes the default <selected_directory> for all subsequent shell and DOS operations. If a drive is specified, it becomes the system's default drive. If a drive is specified but no directory is specified, the current directory of the drive is assumed. LIST *.BAT Lists all <.BAT> files in the current default <selected_directory>. LIST .. Changes the default <selected_directory> from the current directory to its parent and lists all files in the new <selected_directory>. LIST C: Makes the <default_drive> drive <C:> and lists all files in the default directory for the drive. LIST B:\ - 19 - Still River Shell LIST Makes the <default_drive> drive <B:> and lists all files in the root directory of the drive. LIST A:ACCT*.* Assuming the <default_drive> is <C:>, this command changes the <selected_drive> to drive <A:>, assumes the default current directory of the drive <A:> and lists all files in the default directory with <ACCT> in the first four characters of the file name. Options None. - 20 - Still River Shell MOVE 3.7 MOVE Command MOVE <from_file_set> [<to_file_set>] [/Q]<CR> Function The MOVE command establishes the entire contents of the <from_file> under the identity of a new <to_file> name and deletes the <from_file>. Operand 1 <from_file_set> Any standard DOS file specification [<drive>:][\][<directory>\][<file_name>]. Operand 2 <to_file_set> Any standard DOS file specification or blank. Operation If the <to_file> is not established, the <from_file> is not deleted. MOVE PROGA.ASM *.BAK Renames PROGA.ASM to PROGA.BAK within the same directory. MOVE C:\DIRA\*.* A:*.* Copies all files in the DIRA directory of drive C to drive A and deletes all files in DIRA. If the <from_file> and <to_file> occupy the same disk, the MOVE command is executed with a rename. If they do not occupy the same disk, the MOVE is executed with a COPY and a DELETE. Should there be no more room on the target disk, the MOVE prompts: ^insufficient space; retry on new disk? (y/n) If you change the disk and enter <Y>, the MOVE will resume copying the <file_set> starting with the complete file that did not fit on the prior media. You may use as many media as you need to complete the <file_set> move. - 21 - Still River Shell MOVE Options Option (1) Write on existing files Option (3) or </Q> Query on multiple operations. - 22 - Still River Shell OPTIONS 3.8 OPTIONS Command OPTIONS Function The OPTIONS command shows and sets the values of shell system options. Operand 1 None. Operation The OPTIONS command presents a screen which allows you to list and edit the <option_set>. The Option values determine some of the behavior of the shell. You move the cursor to select the Option you wish to edit. The data making up the the option list are switches. Switches are one byte fields with a fixed set of alternative values from which you choose. You change the <selected_option> switch value by striking the <SPACE_BAR>. Option 1 Write over existing files (<Y> | <?>). - <Y> = yes, write on existing files when doing a COPY, MOVE or WRITE just as PC/MS-DOS does. - <?> = prompt if a <to_file> already exists. In the following example, a move instruction encounters an existing <to_file> with the option set to <?>. MOVE *.BAT \DIR1\ ^ \DIR1\RUN.BAT exists; write? (y/n) The directory information of both the <to_file> and the <from_file> are displayed in the Data Window as you are prompted for a decision. - 23 - Still River Shell OPTIONS - <Y> = The existing <to_file> is replaced by the <from_file>. - <N> = The operation is bypassed. Option 2 Remember second operand (<N> | <Y>). - <Y> = place second operand of prior command function into the current command line's second operand position when the command is selected. - <N> = command line starts with a blank second operand. Option (3) or </Q> Query multiple operations (<Y> | <N>). - <Y> = prompt before command execution for each member of the selected set. - <N> = Do not prompt For example: DELETE *.BAT ^ RUN.BAT ? (y/n) - <Y> = execute the operation. - <N> = skip operation; prompt for next operation, if any. The </Q> on appropriate command lines sets Option 3 equal to <Y> for this execution of the command, for example: DELETE *.BAT /Q would present each file in the <.BAT> set before execution. - 24 - Still River Shell RENAME 3.9 RENAME Command RENAME Function To rename a file, use the Shell's MOVE command. Operand 1 Operation Options - 25 - Still River Shell SORT 3.10 SORT Command SORT Function The SORT command sorts the current <file_set> list and determines LIST sort criteria. Operand 1 None. Operation The sort has several subcommands for sorting the <file_set> list based on different criteria. You may enter one or more subcommands selecting the appropriate letter. - DATE/TIME Sorts by file date/time in ascending order. - EXTENSION Sorts by file extension in ascending order. - NAME Sorts by file name in ascending order. - SIZE Sorts by file size in ascending order. When you enter <ESC>, you return to the main Command Selection Line with the <file_set> as you last sorted it. All subsequent LIST command <file_set> lists are sorted by the criteria last selected. Options None. - 26 - Still River Shell TREE 3.11 TREE Command TREE [<selected_directory>] <CR> Function The TREE command displays both the parent and subdirectory structure of the <selected_directory>. In addition, you may "move" up and down the directory structure as well as LIST, MAKE or REMOVE a directory. Operand 1 The <selected_directory> whose parent and subdirectories are to be displayed. Default: Current <selected_directory>. Operation The directory tree is displayed in the Set Window. The <UP/DOWN CURSOR> keys allow you to move the <selector> to any directory in the list. All subcommand operations address the <selected_directory>. - LIST requests a file list of the <selected_directory>. - MAKE creates a named subdirectory under the <selected_directory>. - REMOVE deletes an empty <selected_directory>. - TREE displays the parent and subdirectories of the <selected_directory>. Options None. - 27 - Still River Shell VIEW 3.12 VIEW Command VIEW [<selected_file> <CR>] Function The VIEW command displays the contents of a file in character format. Operand 1 <selected_file>. Operation Normally, you view the <selected_file>. You may specify a file only. If the <selector> is on a directory; then, you may enter a standard DOS file specification [<drive>:][\][<directory>\][<file_name>]. No wild cards, <?> or <*>, permitted. You select what area of the file to view with the <HOME>, <END>, <PAGE UP/DN> and <CURSOR UP/DN>. Options None. - 28 - Still River Shell WRITE 3.13 WRITE Command WRITE <to_file><CR> Function The WRITE command copies the <selected_file_set> list, created by the LIST or FIND commands, to the <to_file>. Operand 1 <to_file> Any standard DOS file specification [<drive>:][\][<directory>\][<file_name>]. Operation The WRITE creates a file which contains all members of the <selected_file_set>. The data appears in the same form as the set is presented in the Set Window by the LIST or FIND commands. The FIND set contains the path and file names of files from one or more directories; the LIST set contains the files and file descriptions of a single directory which satisfy the set definition. Options Option (1) Write on existing files - 29 - Still River Shell XDOS 3.14 XDOS Command XDOS Function The XDOS (execute DOS) command allows you to execute commands under DOS from the shell including prior command recall and full command line edit. Operand 1 None. Operation When you execute the XDOS command, you are presented with a standard DOS prompt showing the current drive and directory on the command line. C:\DOC>_ You may enter any DOS command string. You may edit the command line with the normal shell command line edit features. You may enter as many commands as you wish. As you execute DOS commands and DOS responds, the shell screen moves up and, eventually, off the display as it is replaced by the DOS dialogue. You may recall a prior DOS command line, then edit and execute it. The command line edit functions for XDOS are the same as the shell commands with the exception of these special XDOS edit features: - <ESC> - clears the command line. If the command line is blank, <ESC> escapes the XDOS command presentation and returns to the shell command selection presentation. Please note: the default <selected_drive> or <selected_directory> may have been changed by your DOS commands. - <UP/DOWN CURSOR> - replaces the command line with the selected previous DOS command line from the command stack. The prior command line stack keeps about 20 of your most recent commands to DOS which you can recall, edit and execute. - 30 - Still River Shell XDOS The DOS PATH command can not be used to alter the system path while under XDOS; you must exit the shell to update the system environment. Options None. - 31 - Still River Shell <function_key> 3.15 <function_key> Command <Fn> Function The <function_key> executes a command line under DOS including the state of the shell as parameters. Operand 1 None. Operation When a Function Key, <Fn>, is entered, a command line is executed under XDOS. The command line is <SRF><n><case> <selected_set> <default_drive> <selected_file_path> <selected_file_name> <selected_file_extension> <n> the number of the <function_key> pressed <case> - A = <ALT> - S = <SHIFT> - C = <CTRL> - <null> = <NORMAL> no shift. <selected_set> (%1) Current set description <drive><path><filename> <default_drive> (%2) DOS default drive <selected_file_path> (%3) DOS path, less drive, of the <selected_file> <selected_file_name> (%4) First 8 characters of the <selected_file> name or up to period <selected_file_extension> (%5) Extension of <selected file> - 32 - Still River Shell <function_key> For example, if you pressed <F8> and the <selected_file> was PROGA.C in \SYS\C directory in a LIST (*.C), then the following command is passed to DOS by the shell: SRF8 C:\SYS\C\*.C C \SYS\C PROGA C You must create a SRFn file as either a batch file or program for every function key you plan 2 to use. To make <Function_Key_2>+<ALT> cause the <selected_file> to execute: Define SRF2A.BAT as: %4.%5 When <F2>+<ALT> are pressed, the shell executes the command line: SRF2A C:\SYS\C\*.EXE C: \SYS\C PROGA EXE Which generates: PROGA.EXE Options None. ---------- 2.
