So I have been using Linux for over a year now in an Enterprise setting.
I have to say I am very impressed with its stability and efficiently. I have
10 servers doing DNS, Sendmail, Snort and NFS/Samba sharing. Some of these
servers have been up for over 450 days without a hiccup. That is more than
I can say for my Windows boxes. I still think that Linux has some work ahead
of it to be a contender for a desktop PC but I think it is a much better and
cheaper solution for a server.
This is my Microsoft beginners guide to Linux.
Linux Basics
root = Administrator
"command --help" = same as "command /?" in DOS or Windows
rawrite - Is used to make an installation floppy for Linux
Everything is CaSe sensitive!
Commands you need to know
"mkdir" - Same as md in DOS
"who" - Shows all the log in users
"passwd" - Change your password
"su -" - Allow you to run as root
"pwd" - Show you were you are in the file system
"exit" = logs you out of your Linux session.
ftp - allow you to connect to ftp servers.
open IP/conical name - connects to an ftp server
get filename - retrieves files
put filename - uploads files
bye - quits you ftp session
rpm - Used to install rpm software packages
rpm -Uvh packagename.rpm - This is the command line I have
found to be most useful when installing packages.
ll - Similar to a dir in windows.
ll |more - similar to a dir /p in windows
ll |less - similar to a dir /p in windows
dir - list directories in the current directory
chkconfig - Allows you to turn on/off services
chkconfig --list - List the running services (chkconfig --list
|more) may help to display them a bit more friendly
chkconfig servicesname on - Turns on a service
chkconfig servicesname off - Turns off a service
ifconfig - Similar to ipconfig in widows. In Linux the apapters are eth(x).
ifconfig eth0 off - turns ethernet 0 adapter off
ifconfig eth0 on - turns ethernet 0 apapter on
mount - allows you to mount a cdrom, floppy or a share
cp - simlar to copy in dos/windows
mv - similar to move in DOS/windows
ps -aux - shows all processes for all users
kill - Stops a process
shutdown
shutdown -r 0 - Reboots the PC
shutdown -h 0 - Shuts down the PC
uptime - shows the amount of time Linux has been up
vi - Similar to Edit for DOS, though very different to use.
"up2date -u" - I believe this works in Redhat only.
This is similar to Windows update.
