I have the file script.sh in my-directory folder.
How to run this script with the command `script' from the terminal with no regards to the location I am in the terminal?

You can do so by exporting the path where your script in the PATH environment variable, so that you don't ever have to worry about what your actual script's location is, i.e. if your script is present under say /path/to/dir, do
export PATH=$PATH:/path/to/dir
so that your script's path gets appended to an already existing set if paths under PATH, also remember if you run the above from the command-line, it is not permanent and gets lost soon after the session is terminated. To make it permanent add the same line in .bashrc (or) .bash_profile, depending upon your environment.
Or creating a symbolic link from /usr/bin that is what you intent to do you can do something like ln -s /full/path/to/myscript.sh /usr/bin/myscript and then run as just myscript directly from command line. You can also confirm if is properly added by checking the script's location by which command,
$ which myscript
/usr/bin/myscript

is not there a folder something like `/usr/bin' or something like that where I can create a symlink?

/usr/bin is not meant for adding custom user scripts, but only for shell utilities, however this method does not harm in any way and can be recommended for adding pathless execution of script.Inian
@Cristian: Or if that is what you intent to do you can do something like
ln -s script.sh /usr/bin/script and then run as just script from command line

If you're removing the extension, you should use shebang to specify which interpreter it should use. More info here: https://en.wikipedia.org/wiki/Shebang_(Unix)

@GowthamG: Fair point, depends on which shell the author wants the script to run under,
sh or bash shell. |
Say your directory is /home/Cristian/my-directory then you can make that part of PATH environment variable like export PATH=$PATH:/home/Cristian/my-directory and then you will be able to call it by typing script.sh and not script. If you want it to be called as script then you should name it script and rename the extension.
The export command will make the directory in question part of PATH temporarily. To make it permanent you may want it to part of .bashrc or other shell rc file if you are in other shells.
