2.1.4 Substitution mode option
------------------------------
Some commands accept an option of the form ‘-kSUBST’, used to control
how keywords (⇒Concepts) are expanded in the working file. In
the following table of SUBST values, the example keyword is ‘Revision’
and its value is ‘5.13’.
kv
Generate ‘$Revision: 5.13 $’ (dollar-sign, keyword, colon, space,
value, space, dollar-sign). A locker’s name is inserted in the
value of the ‘Header’, ‘Id’ and ‘Locker’ keyword strings only as a
file is being locked, i.e., by ‘ci -l’ and ‘co -l’. This is the
default substitution mode.
kvl
Like ‘-kkv’, except that a locker’s name is always inserted if the
given revision is currently locked.
k
Generate ‘$Revision$’ (dollar-sign, keyword, dollar-sign). This is
useful when comparing different revisions of a file. Log messages
are inserted after ‘Log’ keywords even if ‘-kk’ is specified, since
this tends to be more useful when merging changes.
o
Like ‘-kkv’, but use the old value present in the working file just
before it was checked in. This can be useful for file formats that
cannot tolerate any changes to substrings that happen to take the
form of keyword strings.
b
Like ‘-ko’, but do all file i/o in binary mode. This makes little
difference on POSIX and Unix hosts, but on DOS-like hosts one
should use ‘rcs -i -kb’ to initialize an RCS file intended to be
used for binary files. Also, on all hosts, rcsmerge normally
refuses to merge files when ‘-kb’ is in effect.
v
Generate ‘5.13’ (value only). Further keyword substitution cannot
be performed once the keyword names are removed, so this should be
used with care. Because of this danger of losing keywords, ‘-kv’
cannot be combined with ‘-l’, and the owner write permission of the
working file is turned off; to edit the file later, check it out
again without ‘-kv’.
