-
- UNIQ is a Shell-command primarily designed to make life easier with file
- name length convention on different file systems such as MSDOS, but it is not
- limited to that. UNIQ takes its input either from stdin or from the contents
- of a specified directory. Its output will give those (file) names that do not
- comply with the requested name length followed by a "UNIQified" name, which
- is unique to the entire input. Thus it is easy to have those files renamed to
- properly comply with the destination filing system name length convention.
-
-
-
- 1. INSTALLATION
- ---------------
-
- Copy UNIQ to any directory you like that is in your path.
-
-
-
- I. USAGE
- --------
-
- uniq [-d[<dir>]] [-a] [-f] [-l<lformat>] [-p<pattern>] [-b<blen>] [-e<elen>]
- -d<dir> : use contents of <dir> as input, otherwise use stdin
- -a : print all names, even those which do not change
- -f : process files only, no dirs (requires -d option)
- -l<lformat> : use <lformat> for formated output ("rename %s %s")
- -p<pattern> : pattern to apply (default #?)
- -b<blen> : max. length of the uniqified string (default 8)
- -e<elen> : max. length of the uniqified extension (default 3)
-
-
-
- II. WHAT IS IT FOR
- ------------------
-
- Suppose you've got a lot of pictures taken from internet news, let's say
- alt/binaries/pictures. Usually no problem for the Amiga, but possibly a
- firend of yours, who's only got a PC running MSDOS, wants to get the
- pictures from you. The problem is that some file names are too long for
- MSDOS, 8 + 3 = 11 chars max file name length. Even worse many pics do have
- allmost the same names except for the last character. If you copy such files
- to a MSDOS floppy or harddisk, you will probably get only one out of several.
- You may rename them by hand, but that's quite annoying, especially if there
- are over 1200 pics in that directory. Now you probably know what UNIQ might
- be used for.
-
-
- III. HOW IT WORKS
- -----------------
-
- UNIQ takes its input, applies the pattern, checks the matched input for
- consistency with the (specified) length and, if necessary, prints a list of
- source names along with their corresponding UNIQified names. The unique
- names will be derived from the source names, modified and attached numbers,
- while the extension will be preserved, maybe truncated. By default UNIQ
- prints 'rename <source file> <unique file>' to stdout. You may redirect
- the output to a file and execute it afterwards to have the job done.
- Remember that by default UNIQ reads from stdin. If you want to use a
- directory as input you have to apply the -d switch (-d is the current,
- -d<dir> is any you specify). No path will be printed. Be aware that all
- arguments to switches must be directly typed after the switch, no spaces
- in between. If reading from stdin without redirection you finish typing by
- pressing CTRL-\ twice.
-
-
- IV. EXAMPLES
- -------------
-
- Let's have UNIQ examine the contents of the current directory and list all
- files which do not comply with the (default) MSDOS name length convention.
- Look at that:
-
- :> uniq -d
-
- Now you can do
-
- :> uniq -d >ram:test.bat
- :> execute ram:test.bat
-
- If you don't want to rename the files you can copy them (see the -a for all)
- Let's say msd: is the MSDOS DISK
-
- :> uniq -d -a -l"copy %s msd:%s" >ram:test.bat
- :> execute ram:test.bat
-
- Or read from stdin
-
- :> uniq -l"this is not uniq: %s should be %s" <testfile.idx

- 2. Inspiration
- --------------
-
- This Program was written, because I had to transfer about 400MB of data
- gathered from UNIX to a MSDOS harddisk.

-
- 3. Misc
- -------
-
- This program is far from complete and has not been tested too much, but it
- works for me.
-
-
- 4. Source
- ---------
-
- I've included the source code. Everybody may use it, implement other
- features etc. as long as the author is mentioned.
