There were some logic problems in my script (the $(...) construct in
bash doesn't return the return value, it returns the output of ...,
similar to the backtick `` construct.). I've fixed them here:
#!/bin/bash
BKUP_HOME=/mnt/backup/home
BKUP_MUSIC=/mnt/backup/music
EXPIRE=/usr/sbin/dirvish-expire
#EXP_OPTS="--quiet"
RUNALL=/usr/sbin/dirvish-runall
#RUN_OPTS="--quiet"
E_MNT_ALREADY_MOUNTED=32
E_UMNT_NOT_MOUNTED=1
E_SUCCESS=0
MNT=/bin/mount
UMNT=/bin/umount
# Mount the backup file systems
$MNT $BKUP_HOME
EXIT_STATUS=$?
if [ "$EXIT_STATUS" -ne "$E_SUCCESS" ];then
if [ "$EXIT_STATUS" -ne "$E_MNT_ALREADY_MOUNTED" ]
then
echo "Failed to mount $BKUP_HOME!" 1>&2
exit $?
fi
fi
$MNT $BKUP_MUSIC
EXIT_STATUS=$?
if [ "$EXIT_STATUS" -ne "$E_SUCCESS" ];then
if [ "$EXIT_STATUS" -ne "$E_MNT_ALREADY_MOUNTED" ]
then
echo "Failed to mount $BKUP_MUSIC!" 1>&2
exit $?
fi
fi
# Run dirvish-expire
$EXPIRE $EXP_OPTS
EXIT_STATUS=$?
if [ "$EXIT_STATUS" -ne "$E_SUCCESS" ]; then
echo "$EXPIRE run failure!" 1>&2
exit $?
fi
# Run dirvish-runall
$RUNALL $RUN_OPTS
EXIT_STATUS=$?
if [ "$EXIT_STATUS" -ne "$E_SUCCESS" ]; then
echo "$RUNALL run failure!" 1>&2
exit $?
fi
# Unmount the backup file systems
$UMNT $BKUP_HOME
EXIT_STATUS=$?
if [[ "$EXIT_STATUS" -ne "$E_SUCCESS" ]]; then
if [[ "$EXIT_STATUS" -ne "$E_UMNT_NOT_MOUNTED" ]]
then
echo "Failed to unmount $BKUP_HOME!" 1>&2
exit $?
fi
fi
$UMNT $BKUP_MUSIC
EXIT_STATUS=$?
if [[ "$EXIT_STATUS" -ne "$E_SUCCESS" ]]; then
if [[ "$EXIT_STATUS" -ne "$E_UMNT_NOT_MOUNTED" ]]
then
echo "Failed to unmount $BKUP_MUSIC!" 1>&2
exit $?
fi
fi
I took out the --quiet options for the time being since I'm getting sh
errors when I run the script from cron. If I get those when my script
runs tomorrow (at roughly 00:00:00), I'll post with more info.
