-
- 1. WHAT IS WHEREIS?
- -------------------
-
- WHEREIS is a utility that searches a disk for files that match a
- user-supplied file specification. The utility performs a recursive search
- through any subdirectories it finds during its search. WHEREIS can be given
- multiple file specifications, and will show all files that match any of the
- given file specifications. WHEREIS can also be instructed to perform a
- DOS command on each of the files that is found.
-
- 2. HOW TO USE WHEREIS
- ---------------------
-
- To search an entire disk for a particular file specification, you would
- execute WHEREIS like this:
-
- whereis *.asm
-
- This would search through the entire drive (the current drive) and display
- each instance of a file matching the file specification *.asm.
-
- You can also provide an explicit drive specifier:
-
- whereis a:\*.asm
-
- This will search drive A: for all matching files.
-
- If you don't want to search an entire disk, you can explicitly define the
- path from which to start the recursive search. For example,
-
- whereis c:\borland\tasm\*.asm
-
- will search for all files matching *.asm in the directory c:\borland\tasm
- and any subdirectories below it.
-
- You can halt execution of WHEREIS by pressing any key while it's running.
- You will be given a message that execution has been interrupted when the
- next file is found. For immediate interruption, press Control-Break. If
- you want to pause execution of WHEREIS, press the space bar. You will be
- given a prompt to press the spacebar a second time to resume the search.
-
- If you want to search for several file specifications, just enter multiple
- file specifications on the command line. For example,
-
- whereis c:\borland\tasm\*.asm *.inc
-
- will search for all the files matching *.asm or *.inc in the directory
- c:\borland\tasm and any subdirectories below it. Note that only the first
- file specification may contain a drive and path specification.
-
- If you want to perform a dos command on each file that WHEREIS finds,
- you can give the dos command in delimiters on the command line. Valid
- delimiters are '', "", or []. The dos command should contain one of the
- following variables, that will substitute a given string on the command
- line used for the dos command:
-
- %1 - Insert full path, filename and extension
- %2 - Filename and extension (no path)
- %3 - Only the path.
- %4 - Only the filename before the extension followed by a .
- %5 - Only the extension, preceded by a .
-
- For example,
-
- whereis *.bak [del %2]
-
- will delete all .BAK files from your drive.
-
- Another example is,
-
- whereis *.asm *.inc [grep -i ideal %2]
-
- which will search all *.ASM and all *.INC files for the word ideal.
-
- When the dos command is given, it will be given in the same directory that
- the file was found in. Note that the DOS command could also be a call to a
- batch file. Whatever command, executable, or batch file, that is specified
- should be reachable with the current PATH environment variable, or a
- specific path to the executable or batch file should be given within the
- delimiters. Also the command should return to the same directory that it
- was called from.
-
- Since WHEREIS calls COMMAND.COM to do the work of executing the given DOS
- command for each file that is found, performance is best if COMMAND.COM
- is placed on a RAM disk and the COMSPEC= environment variable is updated to
- point to the new copy of COMMAND.COM. For a complete discussion of RAM
- disks and how to set the COMSPEC= environment variable, please see your
- DOS manual.
-
-
- 3. HOW TO ASSEMBLE WHEREIS
- --------------------------
-
- In order to assemble WHEREIS, execute the following command on the DOS
- command line:
-
- make -fwhereis
-
- This will execute the command-line make utility MAKE.EXE and pass it the
- make file WHEREIS.MAK. For instructions on assembling specific modules in
- the WHEREIS program, see the comments at the top of each module.
-
- WHEREIS has been rewritten since Turbo Assembler 1.01 to show off some of
- the new features of Turbo Assembler 2.0. The file IWHEREIS.ASM has many of
- the features specially noted. Refer to that file for more details.
