I do not understand the reason why, are you able to explain.
First, I do not see that you piped your output into the while loop as otheus described. You'll need that pipe for $FNAME to make any sense in your while loop. The ' | ' in otheus' example is important.

You need to use command substitution on your "grep" command in the while loop. Either surround the grep command and arguments with back tics ( the ' ` ' below the tilde) or use the "$(<command>)" (with the double quotes) around your grep line. It depends upon your shell and/or system as to which you use.

Lastly, this may just be how you posted the command and you actually might have done it right, but just in case ... Smilie

You need to separate out your commands with either a newline or a semi colon. You should not have 'do' 'grep' and 'echo' all on the same line, unless you have semi colons between each different command. For clarity, I like to put them on separate lines.

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.
