Linux Multiple Commands
Linux allows you to enter multiple commands at one time. The only requirement is that you separate the commands with a semicolon.
Suppose if you want to move a file called "linux.txt" to a directory "linux 1".But directory "linux1" is not created.Then you can use multiple command usage in linux.
eg:mkdir linux 1/; mv linux.txt linux 1/
Running the combination of commands creates the directory and moves the file in one line.
