BashScript shebang


Syntax

  • Use /bin/bash as the bash interpreter:

    #!/bin/bash

  • Search the bash interpreter in the PATH environment variable with envexecutable:

    #!/usr/bin/env bash

Remarks

A common mistake is to try to execute Windows end-line formatted \r\n script files on UNIX/Linux systems, in this case the used script interpreter in the shebang is:

/bin/bash\r

And is obliviously not found but can be hard to figure out.
