Ok. Just getting back into PERL and probably (or most definitely) making a mountain out of a mole hill.
I'm trying to see if a subdirectory exists, and if not, print the slightly modified path of the missing sub to a file. Sounds simple enough. Well here is my elaborate code. Save the snickering. I know it's nuts. There must be a simpler way.
Directory structure is:
/nas/240/234/2311/VMAIL/1
I need to check that the directory /1 exists. If not, print the 2402342311 to a file.
Any help and tolerance is greatly appreciated
I do get the numbers in a file, but the each number gets printed 3 times

SYNOPSIS
shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]
DESCRIPTION
This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments. It
prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.
OPTIONS
The following command line options are available.
-s, --suppress
Supress output. Useful to only test whether a program exists with the help of the return code.
-r, --reverse
Transform a forward path to a subdirectory into a reverse path.
-d, --dirname
Output the directory name of str.
-b, --basename
Output the base name of str.
-m, --magic
Enable advanced magic search for ""perl"" and ""cpp"".
-p, --path path
Search in path. Default is to search in $PATH.
EXAMPLE
# shell script
awk=`shtool path -p "${PATH}:." gawk nawk awk`
perl=`shtool path -m perl`
cpp=`shtool path -m cpp`
revpath=`shtool path -r path/to/subdir`
HISTORY
The GNU shtool path command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
over into GNU shtool.
