executing shell script without calling sh implicitly

Question

I was wondering if it is possible to make a \"link\" in usr/bin (i.e.) that leads to a shell-script.

But I want just to write

% shellscript

Answer 1

In addition to making the script executable and linking it into /usr/bin, as others have suggested, you will also want to add the "shebang" line to the top of the script:

#!/bin/sh

# your commands here

This lets you specify which shell interpreter (bash, bourne shell, c-shell, perl, python...) should be used to execute your script.
