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 '^?'
