How to execute same script independently?
Hello All,

I have one script for example a1.sh. I want to execute the same a1.sh script inside a1.sh script at the end with different parameter such that the second one will run independently. I don't want the second one to take any input from 1st a1.sh. I tried few things like background/exec etc but no luck.

Thanks
Vikram

Could this help you ?
a1.sh
Code:
#!/bin/ksh
if [ "$1" == "RUN" ]
then
        echo "With argument"
        sleep 5
        echo "finished"
        exit 0
fi
echo "Without argument"
a1.sh "RUN" &

Try using nohup

That should help you! Smilie

This is my scenario

Iam running this script as the main script

Code:
./app1.sh -e envxxws -b DUMMY -c BPEL configure deploy

and the below one is the one which iam using at the end of this script and it should be run independently

Code:
while read file
do
/apps/psr/build_dev/vtanwar/app1.sh  -e "$Env_Name" -b DUMMY  -c BPEL -p $file undeploy 
done < /apps/psr/build_dev/vtanwar/vikram/removable-workflows1.lst
exit

Code:
while read file
do
/apps/psr/build_dev/vtanwar/app1.sh  -e "$Env_Name" -b DUMMY  -c BPEL -p $file undeploy 
done < /apps/psr/build_dev/vtanwar/vikram/removable-workflows1.lst
exit

is this the complete script?

If yes, then replace the line /apps/psr/build_dev/vtanwar/app1.sh -e "$Env_Name" -b DUMMY -c BPEL -p $file undeploy

as nohup /apps/psr/build_dev/vtanwar/app1.sh -e "$Env_Name" -b DUMMY -c BPEL -p $file undeploy & This should resolve it Smilie

How about this
Code:
nohup sh -c 'while read file; do /apps/psr/build_dev/vtanwar/app1.sh  -e "$Env_Name" -b DUMMY  -c BPEL -p $file undeploy; done < /apps/psr/build_dev/vtanwar/vikram/removable-workflows1.lst' &
exit

@pravin27: why put that while loop in nohup?
