So, you have installed your favorite linux distro and you are sitting in front of it. Probably you must have heard a lot of frightening things about its console. Here you will see some basic linux commands which will help you to get familiar with linux command line. So let's continue with the linux commands cheatsheet.

But first a few words about a very basic command called man. man comes from manual and it works like this man command_name. With this command you can view information on how to use any command of your system. There is even a man page for man! Try typing man man and you ll get the point. So if want further information and details on a command listed below just type man command_name

Lets get started!

A great list of commands. Some suggested changes:

rm -r name: Change 'as long as' to 'as well as'
rpm -hiv --force package.rpm: Change 'in force way' to 'by force'
rpm -qpil package.rpm: Change 'not installed' to 'not-installed'
rpm -q str: Change 'rpms installed containg' to 'installed rpms containing' (typo here)
shutdown -r 10: This should be 'shutdown -r +10'. The command, as listed, would wait until 10:00 system time.
mount -t vfat /dev/hda1 /mnt/c_drive: Put '1' and 'a' in brackets [(1) and (a)]. Change 'dormat' to 'format'. Also, shouldn't '/dev/hda1' be '/dev/sda1' now?
who: Change 'logged in' to 'logged-in'
exit: Add after 'Exit': 'from console login (ie, logout)'
top: Change to 'Monitor processes in real time'
hostname: Change to 'List the system's hostname'

Thanks for your comment and suggestions geoff_f! I have made all the changes you propose.

I wrote this commands list a couple of years before and haven't updated since then. So, yes hda1 should be sda1 now.

Basic Linux Commands
0
Thank you for the List of Basic Commands for Linux. I have a final practical exam coming up and this is one of the nicest finds so far, since I am allowed to use any notes I want during the practical exam. In 11 weeks of class, who can expect anyone to remember the commands and syntax. I hope to find a little more advanced linux command sheet tonight as the test is tomorrow. Kind of focusing around a Network Administrator who has to be able to do the administration for Linux using the command line.

Linux commands seem a little frustrating for everyone at the beginning but once you use them a 'few' times you can't use Linux without them. smilies/wink.gif

RPM commands vs ARM linux server
0
I have QNAP 219P II which linux NASBACKUP 2.6.33.2 arm5 tel is installed on it. I'm struggling with this machine to add the php oci8 in order to connect to an oracle database.
I followed many ways I found in Internet but no much success so far. As this machine is a small server, some commands such as rpm, yum are not supported.
Is there any hope to get these commands installed on this machine?
Best regards,
