command line - How to check whether a partition is mounted by UUID? - Ask Ubuntu

if have uuid of drive partition, how go finding out whether mounted or not, using command line?

lsblk might help. can print uuid , mount point, so, given uuid, see if mount point not empty:

uuid=foo lsblk -o uuid,mountpoint | awk -v u="$uuid" '$1 == u {print $2}' 

so:

uuid=foo mountpoint=$(lsblk -o uuid,mountpoint | awk -v u="$uuid" '$1 == u {print $2}') if [[ -n $mountpoint ]]     echo mounted else     echo not mounted fi 

since lbslk can act on specific devices, can do:

mountpoint=$(lsblk -o mountpoint "/dev/disk/by-uuid/$uuid" | awk 'nr==2') 

with first method, there won't error if uuid isn't connected disk. second method, lsblk error out if /dev/disk/by-uuid/$uuid doesn't exist.
