How do I find out what version of Linux is running?
This happens sometimes: I ssh into a machine but I forgot (or never knew) what linux distribution it's running.
How can I find out? I'd like a general way to at least solve this problem for the more popular distributions - I don't mind if it involves several steps, but one single command would be ideal :)
See:
"cat /etc/issue" will show the distribution on most platforms, unless someone has modified it.
