The <CODE>ci(1)</CODE> command may also be used to a check a file both in and out of an archive. In their simplest forms, <CODE>ci(1)</CODE> and <CODE>co(1)</CODE> take only the name of the working file. <PRE> ci name_of_work_file </PRE> and <PRE> co name_of_work_file </PRE> The command form <PRE> ci -l name_of_work_file </PRE> checks in the file with locking enabled, and <PRE> co -l name_of_work_file </PRE> <EM>is performed automatically.</EM> That is, <CODE>ci -l</CODE> checks the file out again with locking enabled. <PRE> ci -u name_of_work_file </PRE> checks the file into the archive, and checks it out again with locking disabled. In all cases, the user is prompted for a log message. <P><CODE>ci(1)</CODE> will also create a RCS archive if one does not exist already. <P>If you don't specify a revision, <CODE>ci(1)</CODE> increments the version number of the last revision locked in the archive, and appends the revised working file to it. If you specify a revision on an existing branch, it must be higher than the existing revision numbers. <CODE>ci(1)</CODE> will also create a new branch if you specify the revision of a branch which does not exist. See the <CODE>ci(1)</CODE> and <CODE>co(1)</CODE> man pages for details. <P><CODE>ci(1)</CODE> and <CODE>co(1)</CODE> have various options for interactive and non-interactive use. Again, see the <CODE>ci(1)</CODE> and <CODE>co(1)</CODE> man pages for details. <P> <HR> <A HREF="RCS-6.html">Next</A> <A HREF="RCS-4.html">Previous</A> <A HREF="RCS.html#toc5">Contents</A> </BODY> </HTML>
