why isn't the exit status true?
the code:
do
[ -d ${mk_backup_dir[$i]} ] || mkdir -p ${mk_backup_dir[$i]}
[ $? -ne 0 ] && echo "ERROR: release backup directory creation failed -${mk_backup_dir[$i]}" && exit
done
echo "INFO: Backup directories created"
the result:
mkdir: "/cm/uat_releases/riab/uat/2345": Permission denied
ERROR: release backup directory creation failed - /cm/uat_releases/riab/uat/2345
No such file or directory
INFO: Backup directories created
isn't the exit status of the first command on the 3rd line 'true', so therefore the script will exit '&& exit'? but it doesn't, it carries on and displays 'Backup directories created'.
why?

I'm preparing for exam and one of exams is to write own test command...
I wonder if in unix is a command which just returns exit code you specify..
I know I can easily write a function like this:
exStatus() {
return $1
}
-> my question is rather theoretical
