<<im using knoppix 5.01 installed on the HDD and im in the GUI>>


ok so i have been trying to understand the man pages for copmmands but they use terms in there that i dont understand. its like it was writin for advance users only. for example i do the man page for su and i look at the option -c. this is what it says...."specify a command that will be invoked by the shell by its...." and thats it. what does that mean. i thought the command was su so what is the -c doing to su. also every time i run this command su -c kwrite it says can not connect to x server. what the heck is x server. and the option - what does it mean by sets up the enviroment to what the user would expect if they had logged in directly. i dont uinderstand what they mean by log in directly. direct;ly to what. im sorry if these are all stupid questions, its just i wish the man pages where easier to understand. they have so many terms i dont even understand or ever heard of.
