vc

/usr/ccs/bin/vc [options ] [keyword = value ...]

"Version control." Copy lines from standard input to standard output under control of the vc keywords and arguments within the standard input.

This command is completely unrelated to RCS and to SCCS; it is essentially useless.

Options

-a

Replace control keywords in all lines, including text lines.

-c k

Use k instead of : as the control character.

-s

Suppress warning messages.

-t

If any control characters are found before the first tab in the file, remove all characters up to the first tab.
