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

You can make the shell script executable (chmod +x shellscript.sh). Then you can link to it from /usr/bin (ln -s shellscript.sh /usr/bin/shellscript).
