Recently in Debian Wheezy the dpkg command refuses to work with wildcards, so this is the one-liner alternative. (alternative to #13614)

sudo bash -c "cd /PATH/TO/THE/DIRECTORY;bash"
2014-07-28 20:20:04
User: Zath
Functions: bash sudo

Change current working directory with root permissions.

Place this snippet in your .bashrc to add a new "sudocd" command:

function sudocd { sudo bash -c "cd $1;bash" }

Usage: sudocd DIRECTORY

Please note that if you will use this command to cd into directories with the permissions allowing only root to be in them, you will have to use sudo as a prefix to every command that changes/does something in that directory (yes, even ls).

There are times when a X Window server hangs. When this happens, you can log in on a terminal and kill the Xorg process (i.e. the X Server). This one line command will do the trick.

There is no longer a need to add PGP keys for Ubuntu Launchpad PPA's.

The add-apt-repository command creates a new file for the PPA in /etc/sources.list.d/ then adds the PPA's keys to the apt keyring automatically. No muss, no fuss.

(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")

User: tweet78
Functions: df mkdir mount sudo umount

In my example, the mount point is /media/mpdr1 and the FS is /dev/sdd1

/mountpoint-path = /media/mpdr1


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.

You have an external USB drive or key.

Apply this command (using the file path of anything on your device) and it will simulate the unplug of this device.

If you just want the port, just type :

echo $(sudo lshw -businfo | grep -B 1 -m 1 $(df "/path/to/file" | tail -1 | awk '{print $1}' | cut -c 6-8) | head -n 1 | awk '{print $1}' | cut -c 5- | tr ":" "-")

This command will use the fdisk utility to find all block devices on your system, and overwrite them with data from the /dev/urandom non-blocking random number generator.

CAUTION: This will irrevocably erase EVERY SINGLE physical block storage device visible to the fdisk utility, including plugged USB devices, RAID sets, LVM, etc.
