co(1) MPE/iX Shell and Utilities co(1)

–r[rev]

retrieves the latest revision number that is less than or equal to rev.Ifrev indicates a

branch rather than a revision, the latest revision on that branch is retrieved. If rev is

omitted, the latest revision on the default branch is retrieved (see the –b option for

rcs(1)). rev is composed of one or more numeric or symbolic names separated by a

dot (.). The numeric equivalent of a symbolic ﬁeld is speciﬁed with the –n option of

the commands ci(1) and rcs(1).

–sstate

retrieves the latest revision on the selected branch with a state that is set to state.

–u[rev]

same as –r, except that it unlocks the retrieved revision (if it was locked by the per-

son checking it out). If rev is omitted, –u retrieves the latest revision locked by the

user; if no such lock exists, it retrieves the latest revision on the default branch.

–w[author]

retrieves the latest revision on the selected branch which was checked in by the user

with login name author. If the argument author is omitted, the caller’s login name is

assumed.

–x forces keyword expansion. This option takes precedence over the –K option.

–Yﬁle speciﬁes ﬁle as the local conﬁguration ﬁle.

Keyword Substitution

Strings of the form $keyword$ and $keyword:...$ embedded in the text are replaced with

strings of the form $keyword: value$ where keyword and value are pairs from the Table of

Keywords shown in this man page. Keywords may be embedded in literal strings or com-

ments to identify a revision. To use keyword expansion, you enter strings of the form

$keyword$

in the original ﬁle. On check-out, co replaces these strings with strings of the form

$keyword: value$

If a revision containing strings of the latter form is checked back in, the value ﬁelds is

replaced during the next check-out. Thus, the keyword values are automatically updated on

check-out.

Keyword expansion can be performed in all kinds of ﬁles, including binary ﬁles. If keyword

expansion is inappropriate for your ﬁle, you can specify the –k option of co or add

NoKeywordExpand to your conﬁguration ﬁle. If you wish to remove all previous keyword

expansions, specify the –K option of co.
