I've been playing around with ulimit and I have some questions.
If I raise a limit with $ ulimit -n 10000 is this hard or soft?
If I raise a limit with $ ulimit -n 1025 it works, then I try to lower the limit back to its default 1024 with $ ulimit -n 1024 I get an error. Why?
To edit the /etc/security.limits.conf is it safe to use vim/nano?
