Condition 1

[Yarka]

Hi,
I've a trouble when I execute :

if [ [ ${a}%5 = 0 && ${b}%10 = 1 ] ]; then

How can I do this?

Thanks.

What about this ?
if [[ $((a%5)) = 0 && $((b%10)) = 1 ]]; then

Hope This Helps, PH.

Hi,
In fact, I want to do something as:

cat $1 | while read LINE; do

read LINE
a=`echo "$LINE" | awk -F'\t' '{ print $5 }'`
a=${a:3:2}

if [[ $((a%5)) = 0 && $((a%10)) = 1 ]]; then
.....
echo "if case"
else
.....
echo "else case"
fi
done

But this check is wrong, because for example if a=25 my output is else case and not if case.

Thanks.

if [[ $((a%5)) -eq 0 && $((a%10)) -ne 0 ]]; then

This works well, but sorry, if I want to do he negation of the expression:

if [[ $((a%5)) -eq 0 && $((a%10)) -ne 0 ]]; then

How can I do this?

Thanks.

Either:
if [[ ! ($((a%5)) -eq 0 && $((a%10)) -ne 0) ]]; then
or:
if [[ $((a%5)) -ne 0 || $((a%10)) -eq 0 ]]; then

Hope This Helps, PH.
