Try uname -a. That will give you the Linux kernel information. If the kernel version is less than 2.4.xx (or 2.6.xx) it's older.

[coolirc]

$ uname -a
Linux INFIN_2 2.4.21cmp #1 Mon Dec 6 12:50:57 EST 2004 i586 unknown

Most major distributions these days use the 2.6 kernel (except Slackware and Debian) by default. What are you trying to find out?

i wanna know what version of this linux

So what you're asking is how to find out what distribution you're running?

[spencerf]

this doesn't answer your "distro" question but the $ signs in front of all the commands you listed above tends to suggest that you are only in a regular user mode. Try "su" to root and see if you still get permission denied feedback.

[coolirc]

$ su
su: incorrect password
$
