RSync only if filesystem is mounted
mountpoint seems to be the best solution to this: it returns 0 if a path is a mount point:
#!/bin/bashif [[ `mountpoint -q /path` ]]; then echo "filesystem mounted"else echo "filesystem not mounted"fiFound at LinuxQuestions.
if cut -d' ' -f2 /proc/mounts | grep '^/mnt/remote1$' >/dev/null; then rsync -avz ...fiGet the list of mounted partitions from /proc/mounts, only match /mnt/remote1 (and if it is mounted, send grep's output to /dev/null), then run your rsync job.
Recent greps have a -q option that you can use instead of sending the output to /dev/null.
A quick google led me to this bash script that can check if a filesystem is mounted. It seems that grepping the output of df or mount is the way to go:
if df |grep -q '/mnt/mountpoint$' then echo "Found mount point, running task" # Do some stuff else echo "Aborted because the disk is not mounted" # Do some error correcting stuff exit -1fi
