How do I make a Linux or FreeBSD file an executable file?

You need to use chmod command which is use to change file access permissions as well as to setup an executable permission on file.

General syntax:
chmod +x file-name

For example to setup executable permission on a file called foo.sh (shell script):

$ chmod +x foo.sh

To execute file:

$ ./foo.sh

To setup executable permission on a binary file called bar:

$ chmod +x bar

To execute binary file:

$ ./bar

    Thanks for this. I’m trying to work from the CLI as much as poss. these days. Trouble was I had to keep going back to the GUI to make my simple scripts executable.
