Launching apps from the command line


OK, this is a stupid question

I have just installed an app, a really cool clone of rick Dangerous XRICK

the program works fine, however to launch it u have to type ./xrick

question is what is the difference from the command line between typing

./<program name>

and

<program name>

Sorry for the stupid question, and i am willing to read more if you want to tell me to googleoff...

the ./ forces bash to look in the current working directory for the program, if you don't specify it then bash will search all the paths on $PATH for the program

typing a path starting with a . means that the path is relative to the current working directory. `cd /usr/bin; ./mail` has the same result as typing `/usr/bin/mail` for example

Speciafically looks in current directory for the program. This is called relative path. Alternatively, you can give it an absolute path like /some/directory/program_name.

<program name>
Looks for the program binary in user's path.

Code:
echo $PATH
Type the above command in the shell and you'll see what directories are in your path.

Yes, a soft link would do.

You can also put a link in you menu bar, panel, whatever your distro calls it.

in Ubuntu, eg, you right-click on the panel and follow the instructions
