regexp: /reg'eksp/ n. [Unix] (alt. `regex' or `reg-ex') 1.
Common written and spoken abbreviation for `regular expression', one
of the wildcard patterns used, e.g., by Unix utilities such as
`grep(1)', `sed(1)', and `awk(1)'. These use conventions similar to
but more elaborate than those described under glob. For purposes
of this lexicon, it is sufficient to note that regexps also allow
complemented character sets using `^'; thus, one can specify `any
non-alphabetic character' with `[^A-Za-z]'. 2. Name of a well-known
PD regexp-handling package in portable C, written by revered
Usenetter Henry Spencer <<henry@zoo.toronto.edu>>.
