Linux Basic Command

I have just installed Linux (Fedora 9) as my primary OS on my new laptop (MSI VR340) to widen my experience in the world of IT. I believe many companies use this OS because of its stability and open source.

Below are some basic Linux/UNIX command that I learned when using the said Linux Distributions:

cp

.

mkdir
make directory


rm
remove directory



cat > x.txt
make x.txt file



mv
move command


su
login as root

sudo

# vi /etc/resolv.conf
nameserver 208.67.222.222 (server 1)
nameserver 208.67.220.220 (server 2)

netstat -t
interface statistics


ethtool >
interface media settings and options


rpm -ivh package.rpm
install package.rpm


cd
go to root folder


traceroute
trace route


arp -a
