  • In my example, the mount point is /media/mpdr1 and the FS is /dev/sdd1 /mountpoint-path = /media/mpdr1 filesystem=/dev/sdd1 Why this command ? Well, in fact, with some external devices I used to face some issues : during data transfer from the device to the internal drive, some errors occurred and the device was unmounted and remounted again in a different folder. In such situations, the command mountpoint gave a positive result even if the FS wasn't properly mounted, that's why I added the df part. And if the device is not properly mounted, the command tries to unmount, to create the folder (if it exists already it will also work) and finally mount the FS on the given mount point.

    (mountpoint -q "/media/mpdr1" && df /media/mpdr1/* > /dev/null 2>&1) || ((sudo umount "/media/mpdr1" > /dev/null 2>&1 || true) && (sudo mkdir "/media/mpdr1" > /dev/null 2>&1 || true) && sudo mount "/dev/sdd1" "/media/mpdr1")

  • This is a quick replacement for lspci if you need to know what's in a given system but pciutils is not installed. You then need something that can look up the IDs from pci.ids if you want the verbose output. Show Sample Output

    for device in /sys/bus/pci/devices/*; do echo "$(basename ${device} | cut -c '6-') $(cut -c '3-6' ${device}/class): $(cut -c '3-' ${device}/vendor):$(cut -c '3-' ${device}/device)"; done

  • Necessary for fsck for example. The remount functionality follows the standard way how the mount command works with options from fstab. It means the mount command doesn't read fstab (or mtab) only when a device and dir are fully specified. After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command. It does not change device or mount point.

What Others Think

Well, the device mightn't start with /dev/ in which case you get an error in less. NFS mounts, for example, have a device formatted like host:/exported/dir . Anyway, why less for a single line?
