How to avoid multiple while loop?
Hi,
How can I avoid multiple 'cat while read ....? in my script.
In my script, I am taking the inputs from the temp text file and doing the
(
cat while read input
do
...
...
done
)
task and deleting later.
I know it'll raise the perfomance issue. How to avoid this?

Please explain more, but according to I find it out, you want to do any job after a while not into while. For this purpose, you should define some variable like flag and after while survey them all. Note that this is a programming ability, not technical issue.

To avoid the use of cat, use the read statements as follow:

Code:
while IFS= read -r line
do
  #
  # do your stuff with "$line"
  #
done < FILE
