3. sed Programs
A sed program consists of one or more sed commands,
passed in by one or more of the
‘-e’, ‘-f’, ‘--expression’, and ‘--file’
options, or the first non-option argument if zero of these
options are used.
This document will refer to “the” sed script;
this is understood to mean the in-order catenation
of all of the scripts and script-files passed in.
Each sed command consists of an optional address or
address range, followed by a one-character command name
and any additional command-specific code.
