How to run sh file from another sh file
Create file1.sh
#! /bin/sh
echo "Hello World"
Create file2.sh
#! /bin/sh
details = `./file1.sh`
echo $details
give execute permission
chmod +x file1.sh
chmod +x file2.sh
Now run your file
./file2.sh
Output
Hello World
Take a look at this. If you want to run a script you can use:
./yourscript.sh
If your script has a loop, use:
./yourscript.sh&
If you want to get the console after starting scripts and you don't want to see it's output use:
./yourscript.sh > /dev/null 2>&1 &
So, in the master file you'll have:
./yourscript1.sh > /dev/null 2>&1 &
./yourscript2.sh > /dev/null 2>&1 &
./yourscript3.sh > /dev/null 2>&1 &
They will start together.
