Some Linux Commands

Here are some basic Linux commands. Some are well known and some aren't. I am not a Linux Wizard...far from it...but I am learning some basic linux commands and thought I would share some with other newbies so they to can get more familiar with the terminal command line. These work on my Mandrake 8.1 system. xkill Kills a running program exit Exits the terminal reboot Reboots the system halt Shutsdown the computer startx Starts xwindows from terminal man man(command)shows help files info info(command) shows help files --help (command)--help shows help files su Allow you to login as Super User ls "Lists" the contents of the directory pwd Displays "present working directory" cd cd (name) change directory TO:(name) mkdir mkdir (name) Makes new directory rmdir rmdir (name) Removes directory clear Clears the terminal window date Displays current date and time cal Displays a calander uptime Displays time since last reboot df Displays the disk usage on partitions du Displays disk usage of directory id Displays your identification to system groups Displays groups of current user ulimit -a Displays users limits uname Displays name of machine logged into who Displays "who" is logged on the system w Similar to "who" wall Sends message to all logged in users top Displays cpu processes memory etc ps Displays current running processes ---------------------- RPM's Mandrake and RedHat Check if installed already rpm -q To Install the rpm rpm -ih To Update a program using an rpm rpm -Uvh ---------------------- Bored try this: apropos file List tons of file commands ----------------------- Many of the commands listed above have options that can be added to change the output of that command. To see what they are do a : man (command) and it will show you the options. The command line is hard to learn to use at first ..... really hard for us converted MS$ users :) but it is worth the effort. To start a program "like Opera" type the name at the command prompt: $ opera There are many file commands that I didn't list due to the complexity of them. Read up on them and you can harness the power of your computer from the command line! I have to go read now :)
