Do Shell Script Shebang?

Writing a Shell Script
The most common need for using shebang appears when we're writing shell scripts. “/bin/sh” is actually the symlink to an sh-compatible implementation of sh (Shell Command Language). In most cases, it'll be bash (Bourne-Again SHell), but if we want to secure portability, we should use the symlink.

Do shell scripts need a shebang?

3 Answers. The shebang is only mandatory for those scripts, which shall be executed by the operating system in the same way as binary executables. If you source in another script, then the shebang is ignored.

What is shebang in a shell script?

It is called a shebang or a "bang" line. It is nothing but the absolute path to the Bash interpreter. It consists of a number sign and an exclamation point character (#!), followed by the full path to the interpreter such as /bin/bash. All scripts under Linux execute using the interpreter specified on a first line.
