Direct shebang
suggest changeTo 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
Found a mistake? Have a question or improvement idea?
