Working with files and directories

Entering commands on the same line

To send several commands, one after another, separate each of them with a semicolon. For example:

   $ ls > list ; sort list > list1

This command sequence creates a list of files in a file called list. It then sorts the contents of the file alphabetically and redirects the output into a file called list1. The command after the semicolon is not executed until the command before it has completed; the shell waits for the earlier commands to finish.
