1 | .TH RCSDIFF 1L "" "Purdue University" |
| 2 | .SH NAME | |
| 3 | rcsdiff \- compare RCS revisions | |
| 4 | .SH SYNOPSIS | |
| 5 | \fBrcsdiff\fR [ \fB\-biwt\fR ] [ \fB\-cefhn\fR ] [ \fB\-q\fR ] [ \fB\-r\fIrev1\fR ] [ \fB\-r\fIrev2\fR ] file ... | |
| 6 | .SH DESCRIPTION | |
| 7 | .I Rcsdiff | |
| 8 | runs | |
| 9 | .IR diff (1) | |
| 10 | to compare two revisions of each RCS file given. | |
| 11 | A file name ending in ',v' is an RCS file name, otherwise a | |
| 12 | working file name. \fIRcsdiff\fR derives the working file name from the RCS | |
| 13 | file name and vice versa, as explained in | |
| 14 | .IR co (1L). | |
| 15 | Pairs consisting | |
| 16 | of both an RCS and a working file name may also be specified. | |
| 17 | .PP | |
| 18 | The options \fB\-b\fR, \fB\-i\fR, \fB\-w\fR, \fB\-t\fR, | |
| 19 | \fB\-c\fR, \fB\-e\fR, \fB\-f\fR, and \fB\-h\fR, | |
| 20 | have the same effect as described in | |
| 21 | .IR diff (1); | |
| 22 | option | |
| 23 | \fB\-n\fR generates an edit script of the format used by RCS. | |
| 24 | The option \fB\-q\fR suppresses diagnostic output. | |
| 25 | .PP | |
| 26 | If both \fIrev1\fR and \fIrev2\fR | |
| 27 | are omitted, \fIrcsdiff\fR compares the latest revision on the | |
| 28 | default branch (normally the highest branch on the trunk) | |
| 29 | with the contents of the corresponding working file. This is useful | |
| 30 | for determining what you changed since the last checkin. | |
| 31 | .PP | |
| 32 | If \fIrev1\fR is given, but \fIrev2\fR is omitted, | |
| 33 | \fIrcsdiff\fR compares revision \fIrev1\fR of the RCS file with | |
| 34 | the contents of the corresponding working file. | |
| 35 | .PP | |
| 36 | If both \fIrev1\fR and \fIrev2\fR are given, | |
| 37 | \fIrcsdiff\fR compares revisions \fIrev1\fR and \fIrev2\fR of the RCS file. | |
| 38 | .PP | |
| 39 | Both \fIrev1\fR and \fIrev2\fR may be given numerically or symbolically, | |
| 40 | and may actually be attached to any of the options. | |
| 41 | .SH EXAMPLES | |
| 42 | .nf | |
| 43 | The command | |
| 44 | ||
| 45 | .B " rcsdiff f.c | |
| 46 | ||
| 47 | .fi | |
| 48 | runs \fIdiff\fR on the latest revision on the default branch of RCS file f.c,v | |
| 49 | and the contents of working file f.c. | |
| 50 | .SH DIAGNOSTICS | |
| 51 | The exit status is 0 if there were no differences during the last comparison, | |
| 52 | 1 if there were differences, and 2 if there were errors. | |
