Programs not Executing

Question

So one day randomly a month ago all of my programs that I installed stopped opening when I clicked them. I figured out how to manually run Minecraft since it is a jar file, but other programs not so much.

For example, my Teamspeak client requires you to use a .sh file but when I double click it, nothing happens. Same with a few other programs but my main concern is the Teamspeak client. Any advice?

P.S It is Linux Ubuntu installed onto my HP Chromebook '14

Possibly your environment has been erased... Try:

1. Open a terminal window (I suppose that works, else you couldn't have called Minecraft).

2. Type a system command, say ls. This should show the directory list. I also suspect that to be working

3. Type a command of an installed program, java...

4. Type the name of one of the programs that don't work, and check the screen for error messages. (If there are any, report them here) Eg. type the name of the Teamspeak .sh file.

5. If, in 4., there is a message about the program not being found, type echo $PATH and check if in the long list, separated by :, there is a mention of where your program is installed.

EDIT: If your path is /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games then the OS will look in

/usr/local/bin,
/usr/bin,
/bin,
/usr/local/games
/usr/games

If your games is not in one of these directories it won't work. So, select one of the programs/games that doesn't work, type the name:

your_games<enter>

Does it start or not? If not, is there any message?
