Command-Line Syntax
The syntax for invoking sed has two forms:
sed [options] 'command' file(s) sed [options] -f scriptfile file(s)
The first form allows you to specify an editing command on the command line, surrounded by single quotes. The second form allows you to specify a scriptfile, a file containing sed commands. If no files are specified, sed reads from standard input.
The following options are recognized:
- -e cmd
Next argument is an editing command; not needed unless specifying two or more editing commands.
- -f scriptfile
Next argument is a file containing editing commands.
- -n
Suppress the default output; sed displays only those lines specified with the p command or with the p flag of the s command.
- -V
Display version number.
- --quiet
Same as -n.
- --expression= cmd
Same as -e.
- --file= file
Same as -f.
- --help
Display brief help message with command-line options.
- --silent
Same as -n.
- --version
Same as -V.
