How to write if else in one line in shell?
Space -- the final frontier. This works:
if [ $SERVICESTATEID -eq 2 ]; then echo "CRITICAL"; else echo "OK"; fi
Note spaces after [
and before ]
-- [
is a command name! And I removed an extra $
at the end of $SERVICESTATEID
.
An alternative is to spell out test
. Then you don't need the final ]
, which is what I prefer:
if test $SERVICESTATEID -eq 2; then echo "CRITICAL"; else echo "OK"; fi
Write like this, space is required before and after [
and ]
in shell
if [ 2 -eq 3 ]; then echo "CRITICAL"; else echo "OK"; fi
