Hi Jimmy,

I think I get what you mean.

say file1 is:

HELEN
JOE
FRED
HARRY
TERRY

and file2 is:

hello FRED
bert
JOE
hi there
HARRY
JOHN
PETE was here
hello STEVE

Using the script:
Code:
while read name
do
   found="no"
   while read line
   do
      echo $line | grep $name >/dev/null
      if [ $? -eq 0 ]
      then
         echo $name found in file2
         found="yes"
         break
      fi
   done < file2
   if [ $found = "no" ]
   then
      echo $name not found in file2
   fi
done < file1

You will get the output:

HELEN not found in file2
JOE found in file2
FRED found in file2
HARRY found in file2
TERRY not found in file2

Let me know if this helps.

Cheers
Helen

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files SYNOPSIS
xzcmp [cmp_options] file1 [file2] xzdiff [diff_options] file1 [file2] lzcmp [cmp_options] file1 [file2] lzdiff [diff_options] file1 [file2] DESCRIPTION
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed directly to cmp or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com- pression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncom- pressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp or diff is preserved. The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils. SEE ALSO
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1) BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified. Tukaani 2009-07-05 XZDIFF(1)
