CI(1) UNIX Programmer's Manual CI(1) NAME ci - check in RCS revisions SYNOPSIS ci [ options ] file ... DESCRIPTION _C_i stores new revisions into RCS files. Each file name end- ing in `,v' is taken to be an RCS file, all others are assumed to be working files containing new revisions. _C_i deposits the contents of each working file into the corresponding RCS file. Pairs of RCS files and working files may be specified in 3 ways (see also the example section of _c_o (1)). 1) Both the RCS file and the working file are given. The RCS file name is of the form _p_a_t_h_1/_w_o_r_k_f_i_l_e,v and the working file name is of the form _p_a_t_h_2/_w_o_r_k_f_i_l_e, where _p_a_t_h_1/ and _p_a_t_h_2/ are (possibly different or empty) paths and _w_o_r_k_f_i_l_e is a file name. 2) Only the RCS file is given. Then the working file is assumed to be in the current directory and its name is derived from the name of the RCS file by removing _p_a_t_h_1/ and the suffix `,v'. 3) Only the working file is given. Then the name of the RCS file is derived from the name of the working file by remov- ing _p_a_t_h_2/ and appending the suffix `,v'. If the RCS file is omitted or specified without a path, then _c_i looks for the RCS file first in the directory ./RCS and then in the current directory. For _c_i to work, the caller's login must be on the access list, except if the access list is empty or the caller is the superuser or the owner of the file. To append a new revision to an existing branch, the tip revision on that branch must be locked by the caller. Otherwise, only a new branch can be created. This restriction is not enforced for the owner of the file, unless locking is set to _s_t_r_i_c_t (see _r_c_s (1)). A lock held by someone else may be broken with the _r_c_s command. Normally, _c_i checks whether the revision to be deposited is different from the preceding one. If it is not different, _c_i either aborts the deposit (if -q is given) or asks whether to abort (if -q is omitted). A deposit can be forced with the -f option. Printed 11/24/99 6/29/83 1 CI(1) UNIX Programmer's Manual CI(1) For each revision deposited, _c_i prompts for a log message. The log message should summarize the change and must be ter- minated with a line containing a single `.' or a control-D. If several files are checked in, _c_i asks whether to reuse the previous log message. If the std. input is not a termi- nal, _c_i suppresses the prompt and uses the same log message for all files. See also -m. The number of the deposited revision can be given by any of the options -r, -f, -k, -l, -u, or -q (see -r). If the RCS file does not exist, _c_i creates it and deposits the contents of the working file as the initial revision (default number: 1.1). The access list is initialized to empty. Instead of the log message, _c_i requests descriptive text (see -t below). -r[_r_e_v] assigns the revision number _r_e_v to the checked-in revision, releases the corresponding lock, and deletes the working file. This is also the default. If _r_e_v is omitted, _c_i derives the new revision number from the caller's last lock. If the caller has locked the tip revision of a branch, the new revision is appended to that branch. The new revi- sion number is obtained by incrementing the tip revision number. If the caller locked a non-tip revision, a new branch is started at that revision by incrementing the highest branch number at that revision. The default initial branch and level numbers are 1. If the caller holds no lock, but he is the owner of the file and locking is not set to _s_t_r_i_c_t, then the revision is appended to the trunk. If _r_e_v indicates a revision number, it must be higher than the latest one on the branch to which _r_e_v belongs, or must start a new branch. If _r_e_v indicates a branch instead of a revision, the new revision is appended to that branch. The level number is obtained by incrementing the tip revision number of that branch. If _r_e_v indicates a non-existing branch, that branch is created with the initial revision numbered _r_e_v._1. Exception: On the trunk, revisions can be appended to the end, but not inserted. -f[_r_e_v] forces a deposit; the new revision is deposited even it is not different from the preceding one. Printed 11/24/99 6/29/83 2 CI(1) UNIX Programmer's Manual CI(1) -k[_r_e_v] searches the working file for keyword values to determine its revision number, creation date, author, and state (see _c_o (1)), and assigns these values to the deposited revision, rather than com- puting them locally. A revision number given by a command option overrides the number in the working file. This option is useful for software distri- bution. A revision that is sent to several sites should be checked in with the -k option at these sites to preserve its original number, date, author, and state. -l[_r_e_v] works like -r, except it performs an additional _c_o -_l for the deposited revision. Thus, the deposited revision is immediately checked out again and locked. This is useful for saving a revision although one wants to continue editing it after the checkin. -u[_r_e_v] works like -l, except that the deposited revision is not locked. This is useful if one wants to process (e.g., compile) the revision immediately after checkin. -q[_r_e_v] quiet mode; diagnostic output is not printed. A revision that is not different from the preceding one is not deposited, unless -f is given. -m_m_s_g uses the string _m_s_g as the log message for all revisions checked in. -n_n_a_m_e assigns the symbolic name _n_a_m_e to the number of the checked-in revision. _C_i prints an error mes- sage if _n_a_m_e is already assigned to another number. -N_n_a_m_e same as -n, except that it overrides a previous assignment of _n_a_m_e. -s_s_t_a_t_e sets the state of the checked-in revision to the identifier _s_t_a_t_e. The default is _E_x_p. -t[_t_x_t_f_i_l_e] writes descriptive text into the RCS file (deletes the existing text). If _t_x_t_f_i_l_e is omitted, _c_i prompts the user for text supplied from the std. input, terminated with a line containing a single `.' or control-D. Otherwise, the descriptive text is copied from the file _t_x_t_f_i_l_e. During initiali- zation, descriptive text is requested even if -t is not given. The prompt is suppressed if std. input is not a terminal. Printed 11/24/99 6/29/83 3 CI(1) UNIX Programmer's Manual CI(1) DIAGNOSTICS For each revision, _c_i prints the RCS file, the working file, and the number of both the deposited and the preceding revi- sion. The exit status always refers to the last file checked in, and is 0 if the operation was successful, 1 oth- erwise. FILE MODES An RCS file created by _c_i inherits the read and execute per- missions from the working file. If the RCS file exists already, _c_i preserves its read and execute permissions. _C_i always turns off all write permissions of RCS files. FILES The caller of the command must have read/write permission for the directories containing the RCS file and the working file, and read permission for the RCS file itself. A number of temporary files are created. A semaphore file is created in the directory containing the RCS file. _C_i always creates a new RCS file and unlinks the old one. This strategy makes links to RCS files useless. IDENTIFICATION Author: Walter F. Tichy, Purdue University, West Lafayette, IN, 47907. Revision Number: 3.1 ; Release Date: 83/04/04 .
