it looks like you will use your script as

cat $file|yourscript.ksh

so I took the main loop of your script, encapsulated it into a function within the script

I then have it read every line, use grep to find anything without # so all input to your original loop will be comment free

grep -v the -v flag means find without match to sanitize the input to your function.

You could always keep your original script - the if statement and use

cat $file|grep -v -e "#"|yourscript

and that may rid some of the confusion inside of the script.



I hope this makes scence.

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.
