To reduce execution time
Hi All,

The below script I run daily and it consumes 2 hours approx.
In this I am calling another script and executing the same twice.
Is the loop below the cause for the slow process?Is it possible to finetune the program so that it runs in a much faster way?

The first script:
Code:
#!/bin/ksh

for file in 1 2
do
echo "Started on `date`" | tee -a secondscript.log
secondscript.sh   2>&1| tee -a secondscript.log
echo "Ended on `date`" | tee -a secondscript.log
done

Second script contains hundreds of compilation statements(Those are error free).
