   chk_timehr=$(echo $chk_time | /usr/xpg4/bin/awk -F: '{print $1}')
   chk_timemin=$(echo $chk_time | /usr/xpg4/bin/awk -F: '{print $2}')
if [ "$chk_timehr" != "$timehr" ] && [ "$chk_timemin" != "$timemin" ]
   then
     echo "/home/dg/SM/SMfile"

rcsfreeze

rcsfreeze(1)															      rcsfreeze(1)

NAME

       rcsfreeze - freeze a configuration of sources checked in under RCS

SYNOPSIS

       rcsfreeze [name]

DESCRIPTION

       rcsfreeze assigns a symbolic revision number to a set of RCS files that form a valid configuration.

       The  idea is to run rcsfreeze each time a new version is checked in.  A unique symbolic name (C_number, where number is increased each time
       rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk.

       An optional name argument to rcsfreeze gives a symbolic name to the configuration. The unique identifier is still generated and	is  listed
       in the log file but it will not appear as part of the symbolic revision name in the actual RCS files.

       A log message is requested from the user for future reference.

       The  shell  script  works  only	on  all RCS files at one time. All changed files must be checked in already. Run rcsclean(1) first and see
       whether any sources remain in the current directory.

RESTRICTIONS

       rcsfreeze does not check whether any sources are checked out and modified.

       Although both source file names and RCS file names are accepted, they are not paired as usual with RCS commands.

       Error checking is rudimentary.

       rcsfreeze is just an optional example shell script, and should not be taken too seriously.  See CVS for a more complete solution.

FILES

       version number log messages, most recent first
