.\" $Header: ci.1,v 4.4 86/06/13 09:41:30 bob Exp $ .TH CI 1 "" " " .SH NAME ci \- check in RCS revisions .SH SYNOPSIS .B ci [ options ] file ... .SH DESCRIPTION .I Ci stores new revisions into RCS files. Each file name ending in `\fB,v\fR' is taken to be an RCS file, all others are assumed to be working files containing new revisions. \fICi\fR deposits the contents of each working file into the corresponding RCS file (see also \fIrcsintro(1)\fR). .PP For \fIci\fR to work, the caller's login must be in the access list, unless the access list is empty or the caller is the owner of the file or the caller is superuser. .PP 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 \fIstrict\fR (see \fIrcs\fR(1)). A lock held by someone else may be broken with the \fIrcs\fR command. .PP Normally, \fIci\fR checks whether the revision to be deposited is different from the preceding one. If it is not different, \fIci\fR either aborts the deposit (if \fB-q\fR is given) or asks whether to abort (if \fB-q\fR is omitted). A deposit can be forced with the \fB-f\fR option. .PP For each revision deposited, \fIci\fR prompts for a log message. The log message should summarize the change and must be terminated with a line containing a single `.' or a control-D. If several files are being checked in, \fIci\fR asks whether or not to reuse the log message from the previous file. If the standard input is not a terminal, \fIci\fR suppresses the prompt and uses the same log message for all files. See \fB-m\fR also. .PP The number of the deposited revision can be given by any of the options \fB-r\fR, \fB-f\fR, \fB-k\fR, \fB-l\fR, \fB-u\fR, or \fB-q\fR (see \fB-r\fR below). .PP If the RCS file does not exist, \fIci\fR 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, \fIci\fR requests descriptive text (see \fB-t\fR below). .SH OPTIONS .TP 10 .B \-r\fR[\fIrev\fR] assigns the revision number \fIrev\fR to the checked-in revision, releases the corresponding lock, and deletes the working file. This is also the default. If \fIrev\fR is omitted, \fIci\fR 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 revision 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 \fIstrict\fR, the revision is appended to the trunk. If \fIrev\fR indicates a revision number, it must be higher than the latest one on the branch to which \fIrev\fR belongs, or must start a new branch. If \fIrev\fR 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 \fIrev\fR indicates a non-existing branch, that branch is created with the initial revision numbered \fIrev.1\fR. Exception: On the trunk, revisions can be appended to the end, but not inserted. .TP 10 .B \-f\fR[\fIrev\fR] forces a deposit; the new revision is deposited even it is not different from the preceding one. .TP 10 .B \-k\fR[\fIrev\fR] searches the working file for keyword values to determine its revision number, creation date, author, and state (see \fIco\fR(1)), and assigns these values to the deposited revision, rather than computing them locally. A revision number given by a command option overrides the number in the working file. This option is useful for software distribution. A revision that is sent to several sites should be checked in with the \fB-k\fR option at these sites to preserve its original number, date, author, and state. .TP 10 .B \-l\fR[\fIrev\fR] works like \fB-r\fR, except it performs an additional \fIco -l\fR 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 check in. .TP 10 .B \-u\fR[\fIrev\fR] works like \fB-l\fR, except that the deposited revision is not locked. This is useful if one wants to process (e.g., compile) the revision immediately after check in. .TP 10 .B \-q\fR[\fIrev\fR] quiet mode; diagnostic output is not printed. A revision that is not different from the preceding one is not deposited, unless \fB-f\fR is given. .TP 10 .BI \-m "msg" uses the string \fImsg\fR as the log message for all revisions checked in. .TP 10 .BI \-n "name" assigns the symbolic name \fIname\fR to the checked-in revision. \fICi\fR prints an error message if \fIname\fR is already assigned to another number. .TP 10 .BI \-N "name" same as \fB-n\fR, except that it overrides a previous assignment of \fIname\fR. .TP .BI \-s "state" sets the state of the checked-in revision to the identifier \fIstate\fR. The default is \fIExp\fR. .TP .B \-t\fR[\fItxtfile\fR] writes descriptive text into the RCS file (deletes the existing text). If \fItxtfile\fR is omitted, \fIci\fR prompts the user for text from standard input, terminated with a line containing a single `.' or control-D. Otherwise, the descriptive text is copied from the file \fItxtfile\fR. During initialization, descriptive text is requested even if \fB-t\fR is not given. The prompt is suppressed if standard input is not a terminal. .SH DIAGNOSTICS For each revision, \fIci\fR prints the RCS file, the working file, and the number of both the deposited and the preceding revision. The exit status always refers to the last file checked in, and is 0 if the operation was successful, 1 otherwise. .SH EXAMPLES Suppose the current directory contains a subdirectory `RCS' with an RCS file `io.c,v'. Then all of the following commands deposit the latest revision from `io.c' into `RCS/io.c,v'. .nf .sp ci io.c ci RCS/io.c,v ci io.c,v ci io.c RCS/io.c,v ci io.c io.c,v ci RCS/io.c,v io.c ci io.c,v io.c .fi .SH FILES An RCS file created by \fIci\fR inherits the read and execute permissions from the working file. If the RCS file exists already, \fIci\fR preserves its read and execute permissions. \fICi\fR always turns off all write permissions of RCS files. .sp 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. \fICi\fR always creates a new RCS file and unlinks the old one. This strategy makes links to RCS files useless. .SH LIMITATIONS RCS files are identified by appending `\fB,v\fR' to the end of the working file name. If necessary, RCS shortens the file name so that `\fB,v\fR' can be appended without exceeding the maximum allowable file name length and warns the user accordingly. Since the maximum file name length for HP-UX is 14 characters all working file names should be unique in the first 12 characters to guarantee unique RCS files. .sp The log message may not exceed 2046 bytes. .SH SEE ALSO co(1), ident(1), rcs(1), rcsdiff(1), rcsintro(1), rcsmerge(1), rlog(1), rcsfile(5). .SH BUGS A file with approximately 240 revisions may cause a hashtable overflow. \fICi\fR cannot add another revision to the file until some of the old revisions have been removed. Use the \fIrcs\fR command with the \fB\-o\fR (obsolete) option to remove old revisions.
