We are talking here of return code, not a return value.
a simple script that does
echo 1
will have a return code of 0 (success, the code ran successfully) not 1
(the output of the script).
For example I have a dynamic script like this.
ret=$(mysql -u keepalived -pMYPASSWORD -N -h $1 -e "select val from
keepalived where srv=\"$1\";" LB)
if [ $ret -gt 1 ]
then
exit $ret
else
exit 1
fi
To check return code you have to do:
myscript.sh
echo $?
and that will output the return code of the previous command.
