while :
do
   chk_time=$(ls -l run | awk -F" "  '{ print $8 }')
   chk_timehr=$(echo $chk_time | awk -F: '{print $1}')
   chk_timemin=$(echo $chk_time | awk -F: '{print $2}')
   if [ "$chk_timehr" != "$timehr" ] || [ "$chk_timemin" != "$timemin" ]
   then
     time=$(ls -l run | awk -F" "  '{ print $8 }')
     timehr=$(echo $time | awk -F: '{print $1}')

rcsfreeze

RCSFREEZE(1L)															     RCSFREEZE(1L)

NAME

       rcsfreeze - freeze a configuration of sources checked in under RCS

SYNOPSIS

       rcsfreeze [symbolic revision name]

DESCRIPTION

       The rcsfreeze command has the purpose of assigning a symbolic revision number to a set of RCS files, which form a valid configuration.

       The  idea is to run rcsfreeze each time a new version is checked in. A unique symbolic revision number (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.

       If the command is invoked with an argument, then this argument is used as the symbolic name to freeze a configuration.  The unique  identi-
       fier 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 which is saved for future references.

       The  shell script works only on all RCS files at one time.  It is important that all changed files are checked in (there are no precautions
       against any error in this respect). Run rcsclean(1L) first and see whether any sources remain in the current directory.

FILES

       [RCS/]rcsfreeze.version	for the version number

       [RCS/]rscfreeze.log	for the log messages, most recent log message first.

BUGS

       The program does not check whether there are any sources checked out and modified.
