Thanks a lot for you reply.

Actually this script was already written long back in sunsolaris and I need to migrate it to GNU linux. the exact code is as below

code:
Code:
while [ 1 ]
do
# enter the optional parameter if we need to
set -m
${HOME}/${PROCESS}.pl ${OPTIONAL} 2>&1 > $LOGFILENAME &
#check exit status
status=$?

if [ $status -ne 0 ]
then
echo ${PROCESS}.pl ${OPTIONAL} Job fails with status $status
exit $status
fi
echo $! > ${PID_DIR}/${PROCESS}.perl
chmod 755 ${PID_DIR}/${PROCESS}.perl
cat ${PID_DIR}/${PROCESS}.perl | ${MAIL_BIN} -s "\"${MAIL_HEADING1}\"" ${MAIL_LIST}
fg %+
cat ${PID_DIR}/${PROCESS}.perl | ${MAIL_BIN} -s "\"${MAIL_HEADING2}\"" ${MAIL_LIST}
sleep ${SLEEP};
done
exit 0


1) the main aim of running the perl script in background, is to send PERL script PID to mail when it started.
2) Once the script execution is competed then again script need to notify the finish.
3) here the SLEEP is set to 2
4) When I stared the script its

Code:
> ./script.sh.new new Enable &
[1] 5932
> ${HOME}/${PROCESS}.pl ${OPTIONAL} 2>&1 >$LOGFILENAME

4) when press Ctrl-Z:
Code:
> ${HOME}/${PROCESS}.pl ${OPTIONAL} 2>&1 >$LOGFILENAME
exit
>

* echoing the exit and exiting the current shell but these perl and shell script are running in background. Same case even for Ctrl-C

I want to exit the PERL and SHELL when I pressed the Ctrl-C or Ctrl-Z. Please suggest or send me some sample script to handle these.

colrconv

COLRCONV(1)						      General Commands Manual						       COLRCONV(1)

NAME

       colrconv - hamradio convers client with sound and ncurses color support

SYNOPSIS

       colrconv [options] <host> [<service>]

DESCRIPTION

       This manual page documents briefly the colrconv commands.

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

       Colrconv  is  a modified version of VA3DP's ttylink client. In addition to the basic split screen session it gives you color and sound sup-
       port plus some line editing capabilities, a scroll buffer and a status line.  Also the default service is changed to 3600 (convers).

       A new color is assigned to each user the first time he sends text and this color is used when displaying  any  subsequent  text	from  this
       user. Available colors are green, yellow, cyan, magenta, blue and red.  These are used twice, the second time with BOLD attribute on. After
       the colors run out they are used again.

       Bold red is reserved for special messages (starting with ***) and for private messages (eg. <*oh2bns*>: Hello!).

       Colrconv plays certain sound files when it receives text from the convers bridge.  The files are: callsign.au (eg. oh2bns.au),  unknown.au,
       signedon.au  says.au  and pingpong.au. This feature is still a bit experimental and only works with older convers servers. Also you have to
       make your own .au file. The rsynth package is good at this. See the readme for details. Sound files should go into /usr/lib/colrconv.

OPTIONS

       -nocolor
	      Start colrconv in black and white, even if terminal has color support.

       -c channel
	      Connect to channel number 'channel' at startup.

       -n name
	      Send a '/n name' when connected. When -n is omitted the user's login name is used.

LINE EDITING COMMANDS

       Ctrl-A Goto beginning of line.

       Ctrl-B and Left arrow
	      Go one character backward.

       Ctrl-D Delete character under cursor.

       Ctrl-E Goto end of line.

       Ctrl-F and Right arrow
	      Go one character forward.

       Ctrl-K Kill from cursor to end of line (and store to kill buffer).

       Ctrl-L Repaints the whole screen.

       Ctrl-N and Down arrow
	      Scroll Down.

       Ctrl-P and Up arrow
	      Scroll Up.

       Ctrl-R Reprint current line.

       Ctrl-U Delete current line in total.

       Ctrl-W Erase last word.

       Ctrl-Y Yank kill buffer.

       The scroll buffer can be browsed with arrow keys Up and Down (or Ctrl-P and Ctrl-N), PageUp, PageDown, Home and End keys.

FILES

       If ~/.conversrc exists, it is sent to the server after logging in.  Handy for automatically sending commands like /notify, /who, etc.
