Archive-Name: rename.sh

Here comes a file renaming utility. I know, there are nifty shell scripts
and weird sed commands to achieve the same (not to speak of 'tr'). Yet, I
wrote this program to deal with some file renaming problems I had when I
moved several files from VMS and MSDOS to Unix. Anyway, use it if you can,
otherwise...

To unpack the archive, just strip off everything above the "#! /bin/sh" line,
and feed it into /bin/sh. The archive will unpack into a directory "rename".
Just invoking "make" will compile the stuff.

I have compiled the program under Ultrix, BSD4.2, SunOS3.[2-4]. Oh, I mean,
"compiled successfully"! Any bug reports please to [e-mail].
Comments, etc. also to this address. Please consider that I get lotsa e-mail
every day, so try to keep the messages concise.

Enjoy,

Xreplacement instructions and flags supplied in
X.I specs.
XThe following options are available:
X.IP -i
X(interactive) will prompt the user if the resulting file already exists.
X.IP -v
X(verbose) produces a verbose protocol of what the program does.
X.IP -l
X(lowercase) coerces all characters to lowercase characters before any
Xsubstitutions are performed.
X.IP -t
X(trailing dot) remove any trailing dots from the file names before any
Xsubstitutions are performed.
X.IP -\fIn\fP
X(cut chars) cut the first
X.I n
Xcharacters off the original filename before any substitutions are performed.
X.PP
XThe valid replacement specifications are
X.IP old=new
XReplace all occurrences of
X.I old
Xin a file name by the string
X.I new
X(no recursive substitutions, replacement is done left to right).
X.IP string=
XDelete the substring
X.I string
Xin all file names.
X.IP ^prefix
XUse this prefix for all file names.
X.IP =suffix
XAppend this suffix to all file names.
