X.SH NAME
Xrlog \- print log messages and other information about RCS files
X.SH SYNOPSIS
X.B rlog
X.RI [ " options " ] " file " .\|.\|.
X.SH DESCRIPTION
X.B rlog
Xprints information about \*r files.
XFile names ending in
X.B ,v
Xdenote \*r files; all others denote working files.
XIf a working file is given,
X.B rlog
Xtries to find the corresponding
X\*r file first in an \*r subdirectory and then in the working file's directory,
Xas explained in
X.BR co (1).
X.PP
X.B rlog
Xprints the following information for each
X\*r file: \*r file name, working file name, head (i.e., the number
Xof the latest revision on the trunk), default branch, access list, locks,
Xsymbolic names, suffix, total number of revisions,
Xnumber of revisions selected for printing, and
Xdescriptive text. This is followed by entries for the selected revisions in
Xreverse chronological order for each branch. For each revision,
X.B rlog
Xprints revision number, author, date/time, state, number of
Xlines added/deleted (with respect to the previous revision),
Xlocker of the revision (if any), and log message.
XAll times are displayed in \*g.
XWithout options,
X.B rlog
Xprints complete information.
XThe options below restrict this output.
X.nr n \w'\f3\-V\fP\f2n\fP '+1n-1/1n
X.TP \nn
X.B \-L
XIgnore \*r files that have no locks set.
XThis is convenient in combination with
X.BR \-h ,
X.BR \-l ,
Xand
X.BR \-R .
X.TP
X.B \-R
XPrint only the name of the \*r file.
XThis is convenient for translating a
Xworking file name into an \*r file name.
X.TP
X.B \-h
XPrint only the \*r file name, working file name, head,
Xdefault branch, access list, locks,
Xsymbolic names, and suffix.
X.TP
X.B \-t
XPrint the same as
X.BR \-h ,
Xplus the descriptive text.
X.TP
X.B \-b
XPrint information about the revisions on the default branch, normally
Xthe highest branch on the trunk.
X.TP
X.BI \-d "dates"
XPrint information about revisions with a checkin date/time in the ranges given by
Xthe semicolon-separated list of
X.IR dates .
XA range of the form
X.IB d1 < d2
Xor
X.IB d2 > d1
Xselects the revisions that were deposited between
X.I d1
Xand
X.I d2
Xinclusive.
XA range of the form
X.BI < d
Xor
X.IB d >
Xselects
Xall revisions dated
X.I d
Xor earlier.
XA range of the form
X.IB d <
Xor
X.BI > d
Xselects
Xall revisions dated
X.I d
Xor later.
XA range of the form
X.I d
Xselects the single, latest revision dated
X.I d
Xor earlier.
XThe date/time strings
X.IR d ,
X.IR d1 ,
Xand
X.I d2
Xare in the free format explained in
X.BR co (1).
XQuoting is normally necessary, especially for
X.B <
Xand
X.BR > .
XNote that the separator is
Xa semicolon.
X.TP
X.BR \-l [\f2lockers\fP]
XPrint information about locked revisions only.
XIn addition, if the comma-separated list
X.I lockers
Xof login names is given,
Xignore all locks other than those held by the
X.IR lockers .
XFor example,
X.B "rlog\ \-L\ \-R\ \-lwft\ RCS/*,v"
Xprints the name of \*r files locked by the user
X.BR wft .
X.TP
X.BI \-r revisions
Xprints information about revisions given in the comma-separated list
X.I revisions
Xof revisions and ranges. A range
X.IB rev1 \- rev2
Xmeans revisions
X.I rev1
Xto
X.I rev2
Xon the same branch,
X.BI \- rev
Xmeans revisions from the beginning of the branch up to and including
X.IR rev ,
Xand
X.IB rev \-
Xmeans revisions starting with
X.I rev
Xto the end of the branch containing
X.IR rev .
XAn argument that is a branch means all
Xrevisions on that branch.
XA range of branches means all revisions
Xon the branches in that range.
X.TP
X.BI \-s states
Xprints information about revisions whose state attributes match one of the
Xstates given in the comma-separated list
X.IR states .
X.TP
X.BR \-w [\f2logins\fP]
Xprints information about revisions checked in by users with
Xlogin names appearing in the comma-separated list
X.IR logins .
XIf
X.I logins
Xis omitted, the user's login is assumed.
X.TP
X.BI \-V n
XEmulate \*r version
X.I n
Xwhen generating logs.
XSee
X.BR co (1)
Xfor more.
X.PP
X.B rlog
Xprints the intersection of the revisions selected with
Xthe options
X.BR \-d ,
X.BR \-l ,
X.BR \-s ,
Xand
X.BR \-w ,
Xintersected
Xwith the union of the revisions selected by
X.B \-b
Xand
X.BR \-r .
X.SH EXAMPLES
X.LP
X.nf
X.B " rlog \-L \-R RCS/*,v"
X.B " rlog \-L \-h RCS/*,v"
X.B " rlog \-L \-l RCS/*,v"
X.B " rlog RCS/*,v"
X.fi
X.LP
XThe first command prints the names of all \*r files in the subdirectory
X.B RCS
Xthat have locks. The second command prints the headers of those files,
Xand the third prints the headers plus the log messages of the locked revisions.
XThe last command prints complete information.
X.SH DIAGNOSTICS
XThe exit status is zero if and only if all operations were successful.

X *
X * Revision 5.0 1990/08/22 08:12:47 eggert
X * Don't require final newline.
X * Don't append "checked in with -k by " to logs,
X * so that checking in a program with -k doesn't change it.
X * Don't generate trailing white space for empty comment leader.
X * Remove compile-time limits; use malloc instead. Add -k, -V.
X * Permit dates past 1999/12/31. Make lock and temp files faster and safer.
X * Ansify and Posixate. Check diff's output.
X *
X * Revision 4.8 89/05/01 15:12:35 narten
X * changed copyright header to reflect current distribution rules
X *
X * Revision 4.7 88/11/08 13:54:14 narten
X * misplaced semicolon caused infinite loop

X * warnings)
X *
X * Revision 1.3 87/09/15 16:39:39 shepler
X * added an initializatin of the variables editline and linecorr
X * this will be done each time a file is processed.
X * (there was an obscure bug where if co was used to retrieve multiple files
X * it would dump)
X * fix attributed to Roy Morris @FileNet Corp ...!felix!roy
X *
X * Revision 1.2 87/03/27 14:22:17 jenkins
X * Port to suns
X *
X * Revision 4.1 83/05/12 13:10:30 wft
X * Added new markers Id and RCSfile; added locker to Header and Id.

X * Changed keyword expansion to always print a space before closing KDELIM;
X * Expansion for Header shortened.
X *
X * Revision 3.3 82/11/14 14:49:30 wft
X * removed Suffix from keyword expansion. Replaced fclose with ffclose.
X * keyreplace() gets log message from delta, not from curlogmsg.
X * fixed expression overflow in while(c=putc(GETC....
X * checked nil printing.
X *
