command for version
 

Hi, Iam very new at linux, and so far is been great, is there a command where shows what version of linux do you have, for example, I'am using red hat, hope somebody can help me, thanks!

I believe you can find it using: 'cat /etc/redhat-version'

thanks a lot, I use 'cat /etc/redhat-release', thanks!

For more in-depth info, try:
uname -a

One more way:

cat /proc/version
