this is one of the standard annoyances... the concept of a CDW, PWD, OLDPWD
or whatever is a shell environment variable...
1) so you create a new shell (perl.exe) and cs somewhere and store the
directory in a file... (or whatever)
2) your batch file (running in a cmd.exe of its own) then does a cd to this
same directory
3) then cmd.exe exits and drops you back out in the original CMD.exe in its
original working directory because each shell has its own copy which is
propagated to its kids...
on a unix box you'd be tempted just to do:
#!/bin/sh
#mycd.bat
perl find_dir.pl %1
cd %directory_returned_by_find_dir%
export $NEWDIR=$PWD
exec $SHELL
which probably looks like it works on the surface, but probably doesn't if
you look hard enough (because it starts a new shell)
You'd achieve this on unix by updating the .bashrc or whatever with a cd
$NEWDIR command however you still get a brand new shell which might not be
any use to you.
