Something like:

#!/bin/sh
PATH=/bin:/usr/bin:/usr/ucb
for i in `find /foo`
do
 case $i in
  *RCS) {
       NEW="`dirname $i | sed 's/^\/foo/\/new/'`"
       mv $i $i.old
       ln -s $NEW/RCS $i
       };;
 esac
done


Might work.  I haven't tested it.  You may want to play with find options to
follow symlinks properly.

Subject: [rescue] shell script question


this is really only specifically sun-related in that i'm using solaris,
and this seemed like less of a geeks-list question.

anyway, i've been futzing around for the past hour or so trying to write
what i'm certain should be a simple shell script, but i'm getting no
where quickly.  a simple web search turned up nothing that i didn't
already know.

what i'm tring to do is this:

i've got a bunch of directories (actually, some are symlinks, but that
should be easy enough to handle)

/foo/bar1/.../RCS
/foo/bar2/.../RCS

and i'd like to rename the RCS leaf directories to RCS.old, this part
is pretty simple...  but i also want to create new sym-links in their
place.  ie:

/foo/bar1/.../RCS -> /new/bar1/.../RCS

so the name of the link target is the same except for the first
directory name.  this is where i'm running into problems, since my
string parsing/tokenizing skills are quite lacking when it comes to shell
scripts.

i'd appreciate any pointers/suggestions as to how to go about doing
this.  thanks.
