Solaris 7 (unix) jigsaw.server startup/shutdown script V1.8

Hi !

----

Here comes a new version of the jigsaw.server script (V1.8).

It would be nice if someone would make some comments which platforms are
working and which not.

The script needs little modifications to set the right CLASSPATH, jigsaw's
user/group and home directory, and the file permissions should be set to 700,
othwise
the admin server's password is visible to other users (security leak !!).

TODO:
- script should warn at startup (and log daemon/critical) if jigsaw was
terminated
    using CTRL-C etc. (see logger(1))
- script should be rewritten to use functions
- renaming logs at startup: the script should rename jigsaw's logfiles in the
    syslog-style (e.g. syslog.0, syslog.1 etc.) at startup.
    This will be an optional feature, which is usefull when the server is
restarted
    every night using the "restart_server" option (to get daily logs).

----

Bye,
Roland

#######################################################
# version history
# V1.8 (26.07.1999): - fixed the longstandig (silly!) bug that "ps -ef | grep bla-bla" returns the "grep" line
#                    - "grep" replaced by "fgrep" - smaller, faster...
#                    - reduced the "start" sleep value back to 5 sec...
# V1.7 (29.05.1999): - Changed CLASSPATH for JAVA Project-X Release 2
# V1.6 (12.05.1999): - stop now only starts jigkill if there's a jigsaw-server process running
# V1.5 (07.05.1999): - start: increased the delay from 10 to 20 sec after jigsaw has been invoked because 
#                      some msgs are "eaten" by dtlogin/xdm
# V1.4 (03.05.1999): - added "save" option to save servers
#                    - "stop" option now waits until the "jigkill" background process returns
#                    - fixed delay in stop option (was "sleep 8" instead of "sleep 5"; 
#                      bug introduced in V1.2)
#                    - fixed startup delay (should be 10 sec to see jigsaw's startup messages on console)
# V1.3 (28.04.1999): - changed CLASSPATH for new servlet archive /usr/local/java/jsdk2.1/servlet.jar
#                    - added SIGKILL shutdown method to force a "shutdown" of jigsaw service if SIGTERM 
#                      did not work
#                    - added "restart_server" switch to make "stop" + "start" in one step.
#                      (I did not use the name "restart" because this may be reserved by another /etc/init.d/ 
#                      script functionality...)
# V1.2             : - added "sleep 5" at startup to see servers startup messages before xdm/dtlogin hides 
#                      this info...
# V1.1             : - initial release
