Linux in a Nutshell, 6th Edition

Standard Options

The following options are recognized:

-n

Suppress the default output; sed displays only those lines specified with the p command or with the p flag of the s command.

-e cmd

Next argument is an editing command. Necessary if multiple scripts or commands are specified.

-f file

Next argument is a file containing editing commands.

If the first line of the script is #n, sed behaves as if -n had been specified.

Multiple -e and -f options may be provided, and they may be mixed. The final script consists of the concatenation of all the script and file arguments.
