rcs - change RCS file attributes
SSYYNNOOPPSSIISS
rrccss [ _o_p_t_i_o_n_s ] _f_i_l_e ...
DDEESSCCRRIIPPTTIIOONN
rrccss creates new RCS files or changes attributes of exist-
ing ones. An RCS file contains multiple revisions of
text, an access list, a change log, descriptive text, and
some control attributes. For rrccss to work, the caller's
login name must be on the access list, except if the
access list is empty, the caller is the owner of the file
or the superuser, or the --ii option is present.
Pathnames matching an RCS suffix denote RCS files; all
others denote working files. Names are paired as
explained in ccii(1). Revision numbers use the syntax
described in ccii(1).
OOPPTTIIOONNSS
--ii Create and initialize a new RCS file, but do not
deposit any revision. If the RCS file has no path
prefix, try to place it first into the subdirectory
..//RRCCSS, and then into the current directory. If the
RCS file already exists, print an error message.
--aa_l_o_g_i_n_s
Append the login names appearing in the comma-
separated list _l_o_g_i_n_s to the access list of the RCS
file.
--AA_o_l_d_f_i_l_e
Append the access list of _o_l_d_f_i_l_e to the access
list of the RCS file.
--ee[_l_o_g_i_n_s]
Erase the login names appearing in the comma-
separated list _l_o_g_i_n_s from the access list of the
RCS file. If _l_o_g_i_n_s is omitted, erase the entire
access list.
--bb[_r_e_v]
Set the default branch to _r_e_v. If _r_e_v is omitted,
the default branch is reset to the (dynamically)
highest branch on the trunk.
--cc_s_t_r_i_n_g
sets the comment leader to _s_t_r_i_n_g. The comment
leader is printed before every log message line
generated by the keyword $$LLoogg$$ during checkout (see
ccoo(1)). This is useful for programming languages
without multi-line comments. An initial ccii ,, or an
rrccss --ii without --cc, guesses the comment leader from
GNU 1991/09/26 1
RCS(1) RCS(1)
the suffix of the working file.
--kk_s_u_b_s_t
Set the default keyword substitution to _s_u_b_s_t. The
effect of keyword substitution is described in
ccoo(1). Giving an explicit --kk option to ccoo, rrccssdd--
iiffff, and rrccssmmeerrggee overrides this default. Beware
rrccss --kkvv, because --kkvv is incompatible with ccoo --ll.
Use rrccss --kkkkvv to restore the normal default keyword
substitution.
--ll[_r_e_v]
Lock the revision with number _r_e_v. If a branch is
given, lock the latest revision on that branch. If
_r_e_v is omitted, lock the latest revision on the
default branch. Locking prevents overlapping
changes. A lock is removed with ccii or rrccss --uu (see
below).
--uu[_r_e_v]
Unlock the revision with number _r_e_v. If a branch
is given, unlock the latest revision on that
branch. If _r_e_v is omitted, remove the latest lock
held by the caller. Normally, only the locker of a
revision may unlock it. Somebody else unlocking a
revision breaks the lock. This causes a mail mes-
sage to be sent to the original locker. The mes-
sage contains a commentary solicited from the
breaker. The commentary is terminated by end-of-
file or by a line containing .. by itself.
--LL Set locking to _s_t_r_i_c_t. Strict locking means that
the owner of an RCS file is not exempt from locking
for checkin. This option should be used for files
that are shared.
--UU Set locking to non-strict. Non-strict locking
means that the owner of a file need not lock a
revision for checkin. This option should _n_o_t be
used for files that are shared. Whether default
locking is strict is determined by your system
administrator, but it is normally strict.
--mm_r_e_v::_m_s_g
Replace revision _r_e_v's log message with _m_s_g.
--nn_n_a_m_e[::[_r_e_v]]
Associate the symbolic name _n_a_m_e with the branch or
revision _r_e_v. Delete the symbolic name if both ::
and _r_e_v are omitted; otherwise, print an error mes-
sage if _n_a_m_e is already associated with another
number. If _r_e_v is symbolic, it is expanded before
association. A _r_e_v consisting of a branch number
followed by a .. stands for the current latest
GNU 1991/09/26 2
RCS(1) RCS(1)
revision in the branch. A :: with an empty _r_e_v
stands for the current latest revision on the
default branch, normally the trunk. For example,
rrccss --nn_n_a_m_e:: RRCCSS//** associates _n_a_m_e with the current
latest revision of all the named RCS files; this
contrasts with rrccss --nn_n_a_m_e::$$ RRCCSS//** which associates
_n_a_m_e with the revision numbers extracted from key-
word strings in the corresponding working files.
--NN_n_a_m_e[::[_r_e_v]]
Act like --nn, except override any previous assign-
ment of _n_a_m_e.
--oo_r_a_n_g_e
deletes (outdates) the revisions given by _r_a_n_g_e. A
range consisting of a single revision number means
that revision. A range consisting of a branch num-
ber means the latest revision on that branch. A
range of the form _r_e_v_1::_r_e_v_2 means revisions _r_e_v_1 to
_r_e_v_2 on the same branch, ::_r_e_v means from the begin-
ning of the branch containing _r_e_v up to and includ-
ing _r_e_v, and _r_e_v:: means from revision _r_e_v to the
end of the branch containing _r_e_v. None of the out-
dated revisions may have branches or locks.
--qq Run quietly; do not print diagnostics.
--II Run interactively, even if the standard input is
not a terminal.
--ss_s_t_a_t_e[::_r_e_v]
Set the state attribute of the revision _r_e_v to
_s_t_a_t_e _. If _r_e_v is a branch number, assume the lat-
est revision on that branch. If _r_e_v is omitted,
assume the latest revision on the default branch.
Any identifier is acceptable for _s_t_a_t_e. A useful
set of states is EExxpp (for experimental), SSttaabb (for
stable), and RReell (for released). By default, ccii(1)
sets the state of a revision to EExxpp.
--tt[_f_i_l_e]
Write descriptive text from the contents of the
named _f_i_l_e into the RCS file, deleting the existing
text. The _f_i_l_e pathname may not begin with --. If
_f_i_l_e is omitted, obtain the text from standard
input, terminated by end-of-file or by a line con-
taining .. by itself. Prompt for the text if inter-
action is possible; see --II. With --ii, descriptive
text is obtained even if --tt is not given.
--tt--_s_t_r_i_n_g
Write descriptive text from the _s_t_r_i_n_g into the RCS
file, deleting the existing text.

--VV_n Emulate RCS version _n. See ccoo(1) for details.
--xx_s_u_f_f_i_x_e_s
Use _s_u_f_f_i_x_e_s to characterize RCS files. See ccii(1)
for details.
CCOOMMPPAATTIIBBIILLIITTYY
The --bb_r_e_v option generates an RCS file that cannot be
parsed by RCS version 3 or earlier.
The --kk_s_u_b_s_t options (except --kkkkvv) generate an RCS file
that cannot be parsed by RCS version 4 or earlier.
Use rrccss --VV_n to make an RCS file acceptable to RCS version
_n by discarding information that would confuse version _n.
RCS version 5.5 and earlier does not support the --xx
option, and requires a ,,vv suffix on an RCS pathname.
FFIILLEESS
rrccss accesses files much as ccii(1) does, except that it uses
the effective user for all accesses, it does not write the
working file or its directory, and it does not even read
the working file unless a revision number of $$ is speci-
fied.

The RCS pathname and the revisions outdated are written to
the diagnostic output. The exit status is zero if and
only if all operations were successful.

BBUUGGSS
The separator for revision ranges in the --oo option used to
be -- instead of ::, but this leads to confusion when sym-
bolic names contain --. For backwards compatibility rrccss --oo
still supports the old -- separator, but it warns about
GNU 1991/09/26 4

this obsolete use.
Symbolic names need not refer to existing revisions or
branches. For example, the --oo option does not remove sym-
bolic names for the outdated revisions; you must use --nn to
remove the names.
