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

If you want the script to run in the current shell (e.g. you want it to be able to affect your directory or environment) you should say:

. /path/to/script.sh

or

source /path/to/script.sh

Note that /path/to/script.sh can be relative, for instance . bin/script.sh runs the script.sh in the bin directory under the current directory.
