What does the $ command mean?
 

I'm trying to setup winex to play warcraft on my box and the instructions say that you need to run the command: $ winex Setup.exe from the command line. I get: bash: $: command not found

What am I doing wrong? thx

There are two possible things you're doing wrong. One: you didn't CD to the directory which contains Setup.exe before issuing the command, and Two: you didn't preface the command with ./ to tell Bash that the prog is in the current working directory. You could also run the command from anywhere if you specify the /entire/path/to/Setup.exe when you issue the command.
PS: the $ is the prompt symbol you would see when logged in as user; root would see #. Try the command without the $.

$ is not a command... heh.. don't type it in..

The $ is just the instructions showing you that its a bash prompt running as a non-root user. Just type winex Setup.exe from the folder where Setup.exe is stored.
