comd to konow which distribution im running
 

what is the command to know which distribution of debian Im running..
because if I do a uname -r, I get only the kernel version..
I would like to know for example if it is Debian Sarge or Debian woody..

you could try looking in /etc/version or /etc/release or something (the files vary depending on distro)

unless you run your own kernel i think the debian packaged ones include the version in their package name
