How to compare between files

[Dudek]

Hi there.. I was wondering whether anyone can help me here..

I have ten files which is divided into two groups IN and OUT

the format of the files are

rraIN, rraOUT, rrkIN, rrkOUT, szrIN, szrOUT.....

where the first 3 letters are in a list in another file list.txt which lists

rra
rrk
szr
....etc etc

so basically what i need to do is..

for(each entry in list.txt)
{
if (IN file != OUT file)
{set $variable = 99}
}
# basically it needs to check whether both IN and OUT
# file are identical and if it doesnt set it to 99, run
# another script (success)
if ($variable !=99)
{
run another script
}


so what i need to know is whether the first part is possible or not, can anybody help me on this..?

TIA

JD

Suggest you use diff and check the exit status ($?). If it's 0, the files are identical, if not, they aren't. HTH.

this korn shell script should give you a start:

#!/usr/bin/ksh

for f in $( < list.txt)
do
[tab]print &quot;checking ${f}IN against ${f}OUT&quot;
[tab]ret_val=$?
[tab]if [[ $ret_val -ne 0 ]]
[tab]then
[tab][tab]print &quot; ${f}IN and ${f}OUT differ&quot;
[tab]fi
