Bash script to execute multiple Unix commands

Question

I have some commands that take too long to execute so I need a bash script to execute them serially.

The commands:

cd ~/my_file 
command 1 
command 2
...
command n 

This is on Ubuntu 18.04. How should I do it?

Answer 1

Create a script using nano my-script.sh. Add shebang and the commands or path to commands.

#!/bin/bash
/path/to/command/1
/path/to/command/2
/path/to/command/3

Make it executable using chmod

chmod +x my-script.sh

And run it using

./my-script.sh

Or as a one line command in bash:

command1 && command2 && command3 && commandN

This would execute the commands only if the previous command was executed successfully.
