I am new at scripting ... I can do very basic stuff, but now I need a hand.
I have a local filesystem that only will be mounted when I need to do a backup.
I'm starting with this.
#!/bin/bash export MOUNT=/myfilesystem if grep -qs $MOUNT /proc/mounts; then echo "It's mounted." else echo "It's not mounted."; then mount $MOUNT; fi
As I said, I'm very basic at scripting. I heard that you can check the status of the
mount command by looking at the return codes.
RETURN CODES mount has the following return codes (the bits can be ORed): 0 success 1 incorrect invocation or permissions 2 system error (out of memory, cannot fork, no more loop devices) 4 internal mount bug 8 user interrupt 16 problems writing or locking /etc/mtab 32 mount failure 64 some mount succeeded
I don't know how to check that. Any guidance?
