grep    
n. 文本查找工具

文本查找工具

A {Unix} command for
searching files for lines matching a given {regular
expression} (RE). Named after the {qed}/{ed} editor
subcommand "g/re/p", where re stands for a regular expression,
to Globally search for the Regular Expression and Print the
lines containing matches to it. There are two other variants,
fgrep which searches only for fixed strings and {egrep} which
accepts extended REs but is usually the fastest of the three.

Used by extension to mean "to look for something by pattern".
When browsing through a large set of files, one may speak of
"grepping around". "Grep the bulletin board for the system
backup schedule, would you?" See also {vgrep}.
