The letters grep indicate "Globally search for a Regular Expression and
Print." In standard Unix system editors, the notation is g/re/p where re is
a regular expression. The simplest regular expression is a string of
characters where every character matches itself. More complicated regular
expressions can match any character, any one of a set of characters, or the
beginning or end of a line. Although Celtic influence on the Unix system
predominates over Hebraic, greptz means "belch" in Yiddish. Output from the
grep program looks remarkably similar.
