Now that you have a virtual server setup, you can enjoy the benefits of managing your server as root (super admin). With root level access, you can send commands to your server using a bash terminal. Here are the common commands:

• man - stands for manual. Very useful command if you are just getting started with Linux. You can invoke 'man', followed by any other Linux command (cd, for example) and it will display detailed description and list of all available options.
• cd - cd is short for 'change directory'. Allows browsing between different folders of your VPS.
• cp, mv, rm - great commands for basic file management. You can copy (cp), move (mv) or remove (rm) files/folders this way from your server.
• grep - grep permits you to print lines that match a particular pattern. Useful if you are looking for a phrase or or line in a large text file (logs, for example).
• ls - allows you to list the content of a directory. Using "ls -la" will also show you hidden files/directories (those starting with a dot) and additional attributes, such as permissions and ownership.
• chown, chmod - every file or directory has its own ownerhip rights - user and group. With "chown" you can modify those parameters and "chmod" gives you the ability to change permissions (read, write, execute) for the owner, group and the rest of the users, accessing that file/directory.
• nano, vi - "nano" and "vi" are probably the two most popular Linux text editors. You may find "nano" easier to use, while "vi" appears as the preferred editor among more experienced.
• top, ps - "top" provides you with a periodic update (every five seconds by defaut) of running Linux tasks, while "ps" takes a snapshot of all current processes and prints it on your screen.
• df -h, du -hs - shows you the current overall use of your disk in gygabytes (df -h)."du -hs" calculates the total size of a directory in a human readable format (e.g., 1K 234M 2G).

Here are two bonus commands for checking DESK SPACE and RAM usages: To check out the disk space usage on your server, execute this command: df -h And to see the memory usage: free -m]]> http://newsourcemedia.com/blog/top-10-useful-ssh-terminal-commands/feed/ 2 http://newsourcemedia.com/blog/cant-delete-file-on-external-hard-drive-mac/ http://newsourcemedia.com/blog/cant-delete-file-on-external-hard-drive-mac/#comments Tue, 05 Jan 2010 02:04:29 +0000 admin http://newsourcemedia.com/blog/?p=627 Continue reading →]]> Code: cd /Volumes/disk 2) Type out the remove command on then hidden trash directory.

Try using your Terminal application before restarting.

1. Open the Terminal application.
2. Then type 'df'. This will display a list of all mounted disk items.
3. Find the disk you want to eject.
4. The disk I was looking to unmount displayed like this: "/dev/disk1s1s2 208484 208484 0 100% /Volumes/Alex Model Pix".
5. Above you see first a Unix name "/dev/disk1s1s2" followed by the CD volume name "/Volumes/Alex Model Pix".
6. Now type "hdiutil eject FullUnixName" to eject it.
7. Example: "hdiutil eject /dev/disk1s1s2".

That's it. If this does not work. Just restart or poke a pin inside the hidden eject hole by the disk tray if there is one.]]> http://newsourcemedia.com/blog/eject-or-unmount-a-disk-through-the-terminal/feed/ 8 http://newsourcemedia.com/blog/basic-terminal-commands/ http://newsourcemedia.com/blog/basic-terminal-commands/#comments Mon, 30 Jun 2003 00:22:11 +0000 admin http://newsourcemedia.com/blog/2003/06/29/basic-terminal-commands/ Continue reading →]]> Introduction: There are times that you’ll need to use the Terminal Command-Line Interface (CLI), especially when troubleshooting. Here are a few common Terminal Commands I found to be useful for OS X/Unix newcomers like myself. Preparation: Before we start, open the application called TextEdit in the Applications directory. Change the format to “Make Plain Text” from the “Format” menu (note that this tutorial works with the “Make Rich Text” format as well with a “.rtf” extension; however, I prefer the “.txt” extension because it is the universal cross platform extension for plain text files). Then save the file with the name “test.txt” to your Desktop Now open the Terminal application in the Applications directory. The start up screen will look something like this: Last login: Sun Jan 5 12:51:58 on ttyp1 Welcome to Darwin! alex% Unlike the Mac OS X’s nice Aqua interface, the Terminal will display the file data and directory structure in a raw black and white format. The Terminal usually starts off in your home directory. (user%) So let's get started with a command-line to change the directory to the “Desktop” directory. Commands: 1) cd Cd is short for change directory. This will change the current directory to the directory specified. To access the “Desktop” directory, type: cd Desktop Hit return to execute the command (do this every time to execute each command line). To return to your home directory, type: cd ~ But for now let's keep the path to the “Desktop” (cd Desktop). 2) mkdir Mkdir is short for make directory (make folder). To make a test directory, type: mkdir test 3) pwd Pwd displays the path of the current directory. Type: pwd will display something like this: /Users/alex/Desktop 4) cp Cp is short for copy. To copy the “test.txt” file inside of the “test” directory on the “Desktop”, type: cp /Users/alex/Desktop/test.txt test/test2.txt This placed a copy of the “test.txt” file inside the “test” directory and named it “test2.txt”. Notice after the command “cp” we type “pathdir+old name” space, than “dir+new name”. Change (cd) directory to the “test” directory (see above for help). 5) ls Ls is short for list. Ls will list files in a directory. Type: ls will output. test2.txt 6) mv Mv will change the name of a file. From the test directory type: mv test2.txt test3.txt Notice after the command “mv” we type “old name” space, than “new name”. Type “ls” to check if it worked. 7) rm Rm is short for remove (delete). To remove the “test3.txt” file inside the current directory type: rm test3.txt Or remove a folder with or without items in side sudo rm -rf /path/folder_name 8) man Man is short for manual. For example to display the manual for “rm” type: man rm This will display information about the “rm” command. You can type any command after “man” to access additional information on that topic. 9) “Q” key Q is short for quit. To escape the manual screen, hit the "Q" key: If you have any questions, please search or post a question to the forum.]]> http://newsourcemedia.com/blog/basic-terminal-commands/feed/ 28
