Bash Script shebang Env shebang
Example
To execute a script file with the bash executable found in the PATH environment variable by using the executable env, the first line of a script file must indicate the absolute path to the env executable with the argument bash:
#!/usr/bin/env bash
The env 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
