Hi
Am trying to compare the values of two files..
One is a big file that has many values and the other is a small file..
The big file has all values present in small file..
My problem is when i tried to compare the value present is SmallFile that is not present in BigFile.. My code should return error
But it is returning the return value of grep command as zero
Code:
#!/usr/bin/ksh
#set -x
count=`cat SmallFile | wc -l`
while [[ $count -gt 0 ]] && read LINE ; do
d=$LINE
i=`echo $d | cut -f1 -d " "`
td=`echo $d | cut -f2 -d " "`
fmp=`cat BigFile | grep "$i" | awk -F " " '{print $2}'`
RetVal=`echo $?`
echo "The RC val is $RetVal and i value is $i"
if [[ $RetVal -eq 0 ]]; then
if [[ $td -eq $fmp ]]; then
echo "The values from Small File is $td and from BigFile is $fmp"
fi
else
echo "Cannot find match for $i"
fi
count=$(($count-1))
done < SmallFile
Here the "RetVal" when $i=100000 is one.. But it is returning zero..
Please help..

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
