Executing Shell Scripts On Linux

The script should have execute permissions for the correct owners in order to be runnable.
if you want to execute a shell file called foo.sh

you have to

chmod +x foo.sh

and then you have to execute it by typing

./foo.sh

Example :
here’s a shell file which will display “Hello World” upon successful execution.

#!/bin/bash
echo "Hello, World!"

Save the above code into a file called hello.sh, then to run it you have to follow the below procedure

chmod +x hello.sh
./hello.sh

Output :
Hello, World!
