Sequential Commands
In situations where you wish to execute multiple commands sequentially, ensuring that each finishes before the next starts, you can string them together in a single line using semicolons (;
) as separators:
In this example, I was formatting a huge document and wanted to know how long it would take. The first command date
showed the date and time before the formatting started. The troff
command formatted the document, and then piped the output to the printer. When the formatting was finished, the date and time were printed again, so I knew how long the troff
command took to complete.
Another useful command to add to the end of a long command line is mail
. You could add the following to the end of a command line:
Then, for example, a mail message is sent to the user you choose after the command completes.
