2.4 Invoking ident

ident [options] [file …]

If no file is specified, scan standard input. The ident command scans its input for keywords (see Concepts), displaying to standard output what it finds.

-q

Normally, if no patterns are found for a file, ident emits a warning. This option suppresses the warning.

-V

Note that -Vn is not a valid option for ident, in contrast to most other RCS commands (see Misc common options).

In addition to the normal keyword pattern, for Subversion 1.2 (and later) compatibility³, ident also recognizes patterns having one of the forms:

$keyword:: text $
;; two colons and space after keyword
;; space before ending $

$keyword:: text#$
;; two colons and space after keyword
;; hash before ending $
