I have these similar lines of code all through my korn shell script(my_script.sh). I have many shell scripts (ABC.sh,BAC.sh,CAC.sh,LKJ.sh,POI.sh and many hundreds) which is run through this parent shell script.
Below is my_script.sh:
Code:
echo "ABC.sh started at `date`"
sh ABC.sh
echo "ABC.sh ended at`date`"
echo "BAC.sh started at `date`"
sh BAC.sh 
echo "BAC.sh ended at `date`"
.......................
.......................

Thus it goes on for other files too...

Can I reduce the execution time of my parent script by changing the echo command or date command? I have heard that cat is a better replacement for echo. But will it work in this case?
Probably you could try embedding these multiple commands into a perl script and make use of localtime() instead, so that you dont have to call date command 3000 times or more

If you are using cat, essentially you will have to push that to a file and display from that, am not sure why do you want to do that!!!
