How to run a shell script on a Unix console or Mac terminal?

Question

I know it, forget it and relearn it again. Time to write it down.

Answer 1

Given some script file, call it myscript.sh. Run the command "source myscript.sh".

Answer 2

You must have .sh extension on the file and set the executable permission using chmod

Then you run it by inputting its name at the command prompt.

If you want to run the script in its own shell then you just do > sh filename.sh

Answer 3

# change the perms.

chmod a+x script.bash

# execute

./script.bash
