why do you need to count them and why do you need to print them?

hmmm...... I thouight there was just ONE file.
Now you're saying there're TWO files?

It might be a good idea to post sample INPUT file(s???) [if there're multiples] and instead of outlining the algorithm - outlinie the what needs to be done AND a sample end-result given the sample input/file(s)

Also pls use vB codes when posting code and/quotes - it makes reading the posting much easier.

I could do something like this....But going wrong somewhere...Any ideas will be very much appreciated.


#!/usr/bin/ksh

# put the second column into a file,
# make it unique values

awk '{ print $2 } ' file1 | sort -u > patternfile
# loop thru the patterns from file1
# look for them in file2
while read pattern1
do
/usr/xpg4/bin/grep -q "$pattern1" file2
rc=$?
if [ ${rc} -eq 0 ]; then
echo "Pattern found in file2 -- Successful"
else
echo "Pattern "$Pattern" not found in file2, Failed"
fi
done < patternfile

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
