- Walk V0.1 - Nov. 10, 1987
-
-
- Walk is a CLI utility for performing a given CLI command on a group of
- files. The name arises because the utility "walks" down a given directory
- and all of it's subdirectories, performing the given command on each file
- that matches the optional pattern. The easiest way to explain what walk does
- is to show how it is used, and then discuss the finer points of each of it's
- arguments.
-
- Invoking Walk
-
- Walk "d=Dir" "l=levels" "p=pattern" "+V" "c=Execute string"
-
- where:
-
- Dir is an AmigaDOS type directory ( ram: df1: df0:c sys: fonts: etc. )
-
- The "d=" is mandatory, but quotes are only needed for directories
- containing spaces. The "d" can be in upper or lower case.
-
- levels is an integer indicating how many subdirectories down to scan.
- All directories up to this many levels down will be "walked".
- "l=1" will do only the main directory level. The "l" can be either
- upper or lower case. Quotes here are superfluous, but allowed.
-
- pattern is a standard AmigaDOS wildcard pattern. The "p" can be any
- case. Only files matching the pattern will be affected by the command.
-
- The "+V" ( or "+v" ) command will cause each selected file's name to be
- printed.
-
- The "c=Execute String" tells the program which CLI command to perform on
- the selected files. Two special characters in this string give the
- program most of it's utility. Wherever there is an '@', the currently
- selected filename will be substituted. If your execute string were
- "c=echo @", each of the selected files names would be printed on your
- screen. Another special character is useful when copying and renaming.
- It is the '#' symbol, which backs up one character during expansion.
- This is only really useful immediately after an '@' symbol, for chopping
- a few characters off the end of a filename during a command. For
- instance:
-
- Walk +v p=#?.h "c=rename @ @##.c"
-
- would rename all files ending in ".h" to end with ".c". More than one
- "c=command" string is allowed, in which case the commands are performed
- in the order they are specified. For example:
-
- Walk +v p=#?.c "c=copy @ ram:" "c=delete @"
-
- would copy each file to ram:, then delete the original.
-
- The arguments can be given in any order, and the quotes are only needed
- if the argument contains spaces.
-
- Now I got It & I Know How It Works But What The Hell Do I Do With It?
-
- Have you ever done this:
-
- list >file quick
-
- or this
-
- dir >file opt a
-
- and then edited the resulatnt file into an execute script? Well, this
- program can make using the CLI a lot less drudgerous. You can delete
- all the ".info" files or ".fastdir" files in every directory in one
- fell swoop ( or one swell "foop"). You can rename old Musicraft scores
- to ".smus" files with one command. You can print out all your header
- files quick as you please, or copy them somewhere or whatever.
-
- With this command, the "protect" command is much easier to use, and
- much more useful as well. The "setdate" command also takes on a
- whole new importance. Multi file compiles are much easier on those
- who have no "make" facility. The best way to learn what it can do for you
- is to use it.
-
- WARNING
-
- This program can be very dangerous if used improperly. Power is power and
- it must be handled with care. You might want to try giving no command
- ( yes it's legal ) with verbose on to see which files will be operated
- on. The program responds to <CTRL> 'C', but it will leave locks lying
- around and keep some memory. You will also be left in whatever directory
- was being scanned at the time.
-
- Defaults are 100 for number of levels, the current directory if not
- specified, verbosity off and if no pattern is supplied, "#?" will
- be used.
-
- If for some reason the command you have given is not found, the program
- may hang up. It will also terminate if you alter the contents of the
- directory it is currently in. This would happen if you gave a command
- of "c=delete #?". Needless to say, this is a pretty dumb thing to use
- this program for, but nevertheless it can happen.
-
- These and other bugs/inadequacies will be taken care of in a future
- version, at which time I may also release the source code. The reason
- I am releasing this now is that I thought many people would find it
- useful. Please direct your comments to me via:

- COMING SOON:
-
- A command to reassign EVERYTHING to a different disk without re-booting.
- Actually, the prg. is finished, but I'm too lazy to write docs and
- upload it. If you want it, let me know!
