Hi Ankit:

One way to create a progress bar (dots, a spinning widget, etc.) in a shell script, is to build a function that paints the bar with small sleep intervals between each point. Launch this piece as a background task and capture its pid in a variable, like: TIMER=$!. Start your real work and when that's done, kill the background process that you first started (with 'kill ${TIMER}').

If you prefer, you can do your real work as a background process and let your progress bar or widget spin as a foreground task.

Regards!

Hi James,

Below is my script.
"EMC") echo "its OK"
ssh $srv /usr/symcli/bin/sympd list>/tmp/lun

echo "This is EMC"

echo "So we are extracting LUN ID'S"

while read inputline
do
lun=`cat /tmp/lun|grep $inputline|tr -s " "|cut -d " " -f2`
echo $lun>>disk_lun
echo $lun

done ssh eux290 -n /usr/symcli/bin/sympd list>/tmp/ankit >>>Time _insert_here

Can you bit explain as am running the command using ssh on another server so it will long to track the pid.

can we do time run until we get the control from ssh command.

Regards

Hi (again) Ankit:

Here's an example:

# cat ./monitor
#!/usr/bin/sh
function show_progress
{
while true
do
echo ".\c";
sleep 1
done
}
function do_work
{
echo "...doing work\c"
sleep 15
echo "done!"
}
show_progress &
TIMER=$!
do_work
kill ${TIMER}
sleep 1
exit 0

Regards!

If you want to report the elapsed number of seconds, you can do:

...
T0=${SECONDS}
ssh eux290 -n /usr/symcli/bin/sympd list>/tmp/ankit
echo "elapsed time = $((${SECONDS}-${T0})) seconds"
...
