The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. If pushd is not provided with a path argument , in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories.

For the Unix/Linux shells, this is a feature of the ls command and the terminal.

umount /home/you/dir # or, after finding the associated loop number by e.g. mount | grep "/home/you/dir" # or losetup -a | grep example.img umount /dev/loop<N> At a lower level application programming interface , the association and disassociation of a file with a loop device is performed with the ioctl system call on a loop device.
The join command takes as input two text files and several options. If no command-line argument is given, this command looks for a pair of lines from the two files having the same first field (a sequence of characters that are different from space), and outputs a line composed of the first field followed by the rest of the two lines.
xargs (short for "extended arguments") [1] is a command on Unix and most Unix-like operating systems used to build and execute commands from standard input.It converts input from standard input into arguments to a command.
