Thanks ranj@chn

it's very interesting.

It helps me to get less unuseful data file.

But it's not working as well. If I do the test with a=b and c diff d I always get the same answer rather I should get a=b ok c=d not ok

Sure filename cannot be used for that so I create a function here below :

test ()
{
cat $1 |
grep [*.Z] |
awk '{print $5}' |
sed -e 's/printing//g' -e 's/(8192//g' -e 's/on.//g' -e '/^$/d'

test "$INFOSYSL" > "$DIRLOG/ISL"
test "$INFOSYSF" > "$DIRLOG/ISF"
test "$INFONETL" > "$DIRLOG/INL"
test "$INFONETF" > "$DIRLOG/INF"

a=$ISL
b=$ISF
c=$INL
d=$INF

export a b c d

if [ "$a" -eq "$b" ]; then
echo "Sys File sizes match"
else echo "Sys File sizes differ Errror"
fi >> $MAIL

if [ "$c" -eq "$d" ]; then
echo "net File sizes match"
else echo "Net File sizes differ Errror"
fi >> $MAIL
