The syntax for invoking sed has two forms:
sed [
options
] 'command
'file(s)
sed [
options
] -fscriptfile 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:
Suppress the default output; sed displays only those lines specified with the p command, or with the p flag of the s command.
cmd
Next argument is an editing command; not needed unless specifying two or more editing commands.
file
Next argument is a file containing editing commands.
