Bash Direct shebang


Example

To execute a script file with the bash interpreter, the first line of a script file must indicate the absolute path to the bash executable to use:

#!/bin/bash

The bash path in the shebang is resolved and used only if a script is directly launch like this:

./script.sh

The script must have execution permission.

The shebang is ignored when a bash interpreter is explicitly indicated to execute a script:

bash script.sh
