This is useful +for determining what you changed since the last checkin. +.PP +If +.I rev1 +is given, but +.I rev2 +is omitted, +.B rcsdiff +compares revision +.I rev1 +of the \*o with +the contents of the corresponding working file. +.PP +If both +.I rev1 +and +.I rev2 +are given, +.B rcsdiff +compares revisions +.I rev1 +and +.I rev2 +of the \*o. +.PP +Both +.I rev1 +and +.I rev2 +may be given numerically or symbolically. +.SH EXAMPLE +The command +.LP +.B " rcsdiff f.c" +.LP +compares the latest revision on the default branch of the \*o +to the contents of the working file +.BR f.c . +.SH ENVIRONMENT +.TP +.B \s-1RCSINIT\s0 +Options prepended to the argument list, separated by spaces. +A backslash escapes spaces within an option. +The +.B \s-1RCSINIT\s0 +options are prepended to the argument lists of most \*r commands. +Useful +.B \s-1RCSINIT\s0 +options include +.BR \-q , +.BR \-V , +.BR \-x , +and +.BR \-z . +.TP +.B \s-1RCS_MEM_LIMIT\s0 +Normally, for speed, commands either memory map or copy into memory +the \*o if its size is less than the +.IR memory-limit , +currently defaulting to ``unlimited''. +Otherwise (or if the initially-tried speedy ways fail), +the commands fall back to using +standard i/o routines. +You can adjust the memory limit by setting +.B \s-1RCS_MEM_LIMIT\s0 +to a numeric value +.IR lim +(measured in kilobytes). +An empty value is silently ignored. +As a side effect, specifying +.B \s-1RCS_MEM_LIMIT\s0 +inhibits fall-back to slower routines. +.TP +.B \s-1TMPDIR\s0 +Name of the temporary directory. +If not set, the environment variables +.B \s-1TMP\s0 +and +.B \s-1TEMP\s0 +are inspected instead and the first value found is taken; +if none of them are set, +a host-dependent default is used, typically +.BR /tmp . +.SH DIAGNOSTICS +Exit status is 0 for no differences during any comparison, +1 for some differences, 2 for trouble. +.ds EY 1990, 1991, 1992, 1993 +.SH IDENTIFICATION +Author: Walter F.
