lol... New to linux, probably. My brother has the same problem. If your having excessive trouble, then log into a user and add this to ~./bash_profile (On kde enviroments, type kwrite ~./bash_profile into the konsole. On gnome environments, write gedit ~./bash_profile into the gnome terminal. Try both if you don't know which. if all else fails, try xedit ~./bash_profile)
Add the following to the file
PATH=$PATH:./
export PATH
Save and exit. Now this user can execute commands without ./ in front of them.
edit: if it didn't work, do it again. I posted the wrong thing...
