ci(1) ci(1)NAME ci - check in RCS revisions SYNOPSIS ci [-r[rev]] [-f[rev]] [-k[rev]] [-l[rev]] [-u[rev]] [- q[rev]] [-mmsg] [-nname] [-Nname] [-sstate] [-t[txtfile]] files DESCRIPTION ci stores new revisions into RCS files. Each filename end- ing in ,v is taken to be an RCS file and all others are as- sumed to be working files containing new revisions. ci de- posits the contents of each working file into the corresponding RCS file. Pairs of RCS files and working files may be specified in three ways (see also the example section of co(1)). (1) Both the RCS file and the working file are given. The RCS filename is of the form path1/workfile,v and the working filename is of the form path2/workfile, where path1 and path2 are (possibly different or empty) paths and workfile is a filename. (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 path1/ 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 removing path2/ and appending the suffix ,v. If the RCS file is omitted or specified without a path, then ci looks for the RCS file, first in the directory ./RCS and then in the current directory. For ci to work, the caller's login must be on the access list, unless the access list is empty or the caller is the superuser or the owner of the file. To append a new revi- sion 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 strict (see rcs(1)). A lock held by someone else may be broken with the rcs command. Normally, ci checks whether the revision to be deposited is different from the preceding one. If it is not different, ci either cancels the deposit (if -q is given) or asks whether to cancel (if -q is omitted). A deposit can be forced with the -f option. April, 1990 1
ci(1) ci(1)For each revision deposited, ci 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, ci asks whether to reuse the previous log message. If the standard input is not a terminal, ci 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, ci 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, ci requests descriptive text (see -t). Options -r[rev] assigns the revision number rev to the checked-in revision, releases the corresponding lock, and deletes the working file. This is also the de- fault. If rev is omitted, ci 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 re- vision 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 is the owner of the file, and locking is not set to strict, then the revision is appended to the trunk. If a revision number is indicated by rev, it must be higher than the latest one on the branch to which rev belongs, or rev must start a new branch. If rev 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 rev indicates a non-existing branch, that branch is created with the initial revision numbered rev.1. Exception: On the trunk, revisions can be append- ed to the end but not inserted. -f[rev] forces a deposit; the new revision is deposited 2 April, 1990
ci(1) ci(1)even though it is the same as the preceding one. -k[rev] searches the working file for keyword values to determine its revision number, creation date, au- thor, and state (see co(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, au- thor, and state. -l[rev] works like -r, except it performs an additional co -l for the deposited revision. Thus, the deposit- ed 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[rev] works like -l, except that the deposited revision is not locked. This is useful if one wants to process (that is, compile) the revision immediate- ly after checkin. -q[rev] quiet mode; diagnostic output is not printed. A revision that is the same as the preceding one is not deposited, unless -f is given. -mmsg uses the string msg as the log message for all re- visions checked in. -nname assigns the symbolic name name to the number of the checked-in revision. ci prints an error mes- sage if name is already assigned to another number. -Nname same as -n, except that it overrides a previous assignment of name. -sstate sets the state of the checked-in revision to the identifier state. The default is Exp. -t[txtfile] writes descriptive text into the RCS file (deletes the existing text). If txtfile is omitted, ci prompts the user for text supplied from the stan- dard input, terminated with a line containing a single . or CONTROL-D. Otherwise, the descriptive text is copied from the file txtfile. During ini- tialization, descriptive text is requested even if April, 1990 3
ci(1) ci(1)-t is not given. The prompt is suppressed if standard input is not a terminal. DIAGNOSTICS For each revision, ci 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 if otherwise. FILE MODES An RCS file created by ci inherits the read and execute per- missions from the working file. If the RCS file already ex- ists, ci preserves its read and execute permissions. ci al- ways 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. ci always creates a new RCS file and unlinks the old one. This strategy makes links to RCS files useless.
