chrisfromgreece Also i don't know why some applications folders like /sbin etc is not on Path and i can't execute these commands.
They should be in the default PATH. Find out f you're overriding them somewhere.
chrisfromgreece Also the backspace key doesn't work i haven't selected any layout and when i select english-america still i can't use these keys why is that ??
What character the physical BACKSPACE key produces depends on multiple things, but, generally it should produce either ^H (the ASCII BS char.) or ^? (the ASCII DEL char.). The NetBSD system console outputs ^? if you press BS; xterm, by default (it can be changed), outputs ^H (Similarly, you can configure the behaviour of the DEL key--either to erase the character under the cursor, or to remove the char. before the cursor).
If you've configured one, while the system or program expects the other, then BS won't work as expected.
To see what the BS key will produce do this: At a command prompt, type cat; then type Ctrl-V; then press the BS key. That will tell you what the system console, or xterm, sends. Then, make sure that the system understands that key. Run stty -a; and look at what erase =. Make it match using stty erase '^H' or stty erase '^?'
