OK, it's prounounced "doo-mah"

Thanks for cluing me in with your 'echo $LINE2'
I was doing a few things wrong:

  1. Storing the filepath component of the grep output in a variable called $PATH (Doh!) I've changed it to $FILEPATH
  2. Suppressing the output of the process so only errors were appearing--the grep was actually working, but I assumed the errors were caused by it because at one point, likely prior to my initial quoting effort, grep was throwing an error.
  3. Failing to realize the wordsplitting error was coming from a deeper command in output processing, where I was capturing the file mod date of files tagged by grep (i.e. `ls -e $DIRPATH...`)
Now I've double-quoted all vars with path refs, changed the var names so as not to conflict, and for good measure, redirected standard error to a file.

Thanks for lubing my brain!

Cheers,
Dave

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
