Synopsis

                  co [options] files
               

Retrieve a previously checked-in revision, and place it in the corresponding working file (or print to standard output if -p is specified). If you intend to edit the working file and check it in again, specify -l to lock the file. co accepts the standard options -q, -V, -x, and -z.

Options

-d date

Retrieve latest revision whose checkin timestamp is on or before date.

-f[R]

Force the working file to be overwritten.

-I[R]

Interactive mode; prompt user even when standard input is not a terminal.

-j R2:R3

This works like rcsmerge. R2 and R3 specify two revisions whose changes are merged (joined) into a third file: either the corresponding working file or a third revision (any R specified by other co options).

-k c

Expand keyword symbols according to flag c, which can be:

b

Like o, but perform its operations in binary mode, generating the previous revision’s keywords and values in binary.

k

Expand symbols to keywords only (no values). Useful for ignoring trivial differences during file comparison.

kv

Expand symbols to keyword and value (the default). Insert the locker’s name only during a ci -l or co -l.

kvl

Like kv, but always insert the locker’s name.

o

Expand symbols to keyword and value present in previous revision. This is useful for binary files that don’t allow substring changes.

v

Expand symbols to values only (no keywords). This prevents further keyword substitution and is not recommended. Cannot be used with -l.

-l[R]

Same as -r, but also lock ...
