mkdir command
Hi all, i am new to Linux and need some help.
I used the command: mkdir super
Directory super is created
When i try to change to this directory using: cd /super
I get: bash: cd: /super: No such file or directory
when i use: rm super
I get: rm: cannot remove 'super': Is a directory
What could be the problem?

KILL(2) System Calls Manual KILL(2)
NAME
kill - send signal to a process
SYNOPSIS
kill(pid, sig);
DESCRIPTION
Kill sends the signal sig to the process specified by the process number in r0. See signal(2) for a list of signals.
The sending and receiving processes must have the same effective user ID, otherwise this call is restricted to the super-user.
If the process number is 0, the signal is sent to all other processes in the sender's process group; see tty(4).
If the process number is -1, and the user is the super-user, the signal is broadcast universally except to processes 0 and 1, the scheduler
and initialization processes, see init(8).
Processes may send signals to themselves.
SEE ALSO
signal(2), kill(1)
DIAGNOSTICS
Zero is returned if the process is killed; -1 is returned if the process does not have the same effective user ID and the user is not
super-user, or if the process does not exist.
ASSEMBLER
(kill = 37.)
(process number in r0)
sys kill; sig
