test if string contains another string
I have already received one answer a part of my problem and I thought I could move on without help from there but I am failing miserably.

I am using a source control system called mercurial which, from /bin/sh script I can do this:

Code:
requiredText="This file has been modified"
hgLogOutput=`hg log -v -r $HG_NODE`
filePaths="${hgLogOutput#*files: }" filePaths="${filePaths%description:*}"

declare -a Array=($filePaths)
for filePath in $filePaths; do
    requiredText=hg cat $filePath | grep -F $requiredText
done

You may be able to see that my code fails on the:

Code:
requiredText=hg cat $filePath | grep -F $requiredText

I am trying to check if:

Code:
hg cat $filePath

contains the:

Code:
$requiredText

shell programming has to be the most difficult language I can imagine. Any help appreciated; it has taken me a day to write that which I have so far - and even then with help!

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.
