This one will tell you all current ports in use

since this is a terminal thread I've got a noob question
How do I add a user to the sudoers file? I'm having some trouble doing so and google searches aren't really helping.
I'm on Fedora 25

sudo nano/etc/hostname
rename to nigger
ctrl + X

sudo apt install sl

Visudo if you want to manually add the user into the sudoers file. Otherwise, you can just add your account into the wheel group, which is already in the sudoers file, and have it done that way.

been a LONG time sense I wrote it down, but effectively it should wipe the directory.
I might be wrong but I think the X is to be replaced with a-b-etc.
I used it to wipe the grub partition.

>>60525349
The purpose of cat is to concatenate (or catenate) files. If it is only one file, concatenating it with nothing at all is a waste of time, and costs you a process.

>>60525371
Yeah but it also prints it genius. Also commands get appropriated for other uses all the time so deal with it. For example the touch command is meant to edit file modification times.

No, it's just a wrapper around the same libopus library.
--comp is the opusenc equivalent of the -compression_level parameter in ffmpeg/libopus. It already defaults to 10 for highest encoding complexity + slowest encoding time in either case and can be omitted.

everyone here is a retard. use the visudo command, everything should be self-explanatory from there. If you don't know how to use vi, try 'export EDITOR=nano' and run it again.
