Linux allows you to enter multiple commands at one time. The only requirement is that you separate the commands with a semicolon.
Suppose you have downloaded a new file called foobar-1.3-2.i386.rpm, and you want to put it in a new subdirectory within your home directory called rpms/, but the subdirectory has not been created. You can combine both the creation of the rpms/ directory and the moving of your downloaded file into the directory by typing the following at a shell prompt:
mkdir rpms/; mv foobar-1.3-2.i386.rpm rpms/ |
Running the combination of commands creates the directory and moves the file in one line.
