Linux Shell Commands - Part 3

In This Post, I will Show Directory Traversal and How To Create Folders.

Computer Korner

To Traverse through directory, 'cd'  command is used

When you start the Konsole Or Terminal You are in the Home Directory.

To Move into a sub directory or directory 'cd <dir name>', 'pwd' reveals the current directory path

root@bt:~# cd Desktop/
root@bt:~/Desktop# pwd
/root/Desktop
root@bt:~/Desktop# cd Ckorner/
root@bt:~/Desktop/Ckorner# pwd
/root/Desktop/Ckorner

To go back one directory, 'cd ..' (cdspacedotdot)
root@bt:~/Desktop/Ckorner# cd ..
root@bt:~/Desktop# pwd
/root/Desktop

To go back two directory, 'cd ../..' (cdspacedotdotslashdotdot)
root@bt:~/Desktop/Ckorner# cd ../..
root@bt:~# pwd
/root

'cd' with no option, returns to the HOME directory regardless of wherever you are in the directory path.
root@bt:~# cd Desktop/Ckorner/
root@bt:~/Desktop/Ckorner# pwd
/root/Desktop/Ckorner
root@bt:~/Desktop/Ckorner# cd
root@bt:~# pwd
/root
root@bt:~#

Same as the previous, 'cd ~' , returns to the HOME directory regardless of wherever you are in the directory path.
root@bt:~/Desktop/Ckorner# pwd
/root/Desktop/Ckorner
root@bt:~/Desktop/Ckorner# cd ~
root@bt:~# pwd
/root
root@bt:~#

'cd /' changes to root directory.
root@bt:~# cd Desktop/Ckorner/
root@bt:~/Desktop/Ckorner# pwd
/root/Desktop/Ckorner
root@bt:~/Desktop/Ckorner# cd /
root@bt:/# pwd
/
root@bt:/#

Next, I will show how to make a Folder., command used is 'mkdir <foldername>', to make hidden folder, 'mkdir .<name>'
root@bt:~/Desktop/Ckorner# mkdir post3
root@bt:~/Desktop/Ckorner# cd post3/
root@bt:~/Desktop/Ckorner/post3# mkdir AnotherFolder
root@bt:~/Desktop/Ckorner/post3# mkdir .hiddenFolder
root@bt:~/Desktop/Ckorner/post3# ls -l
total 4
drwxr-xr-x 2 root root 4096 2012-07-08 14:50 AnotherFolder
root@bt:~/Desktop/Ckorner/post3# ls -la
total 16
drwxr-xr-x 4 root root 4096 2012-07-08 14:50 .
drwxr-xr-x 5 root root 4096 2012-07-08 14:50 ..
drwxr-xr-x 2 root root 4096 2012-07-08 14:50 AnotherFolder
drwxr-xr-x 2 root root 4096 2012-07-08 14:50 .hiddenFolder
root@bt:~/Desktop/Ckorner/post3# cd AnotherFolder/
root@bt:~/Desktop/Ckorner/post3/AnotherFolder# ls
root@bt:~/Desktop/Ckorner/post3/AnotherFolder# cd ..
root@bt:~/Desktop/Ckorner/post3# cd .hiddenFolder/
root@bt:~/Desktop/Ckorner/post3/.hiddenFolder# pwd
/root/Desktop/Ckorner/post3/.hiddenFolder
root@bt:~/Desktop/Ckorner/post3/.hiddenFolder# cd ~
root@bt:~#


'ls' command is used to check the files/folders and sub-folders in a Directory

More About 'ls' in later posts. Thats All For this post.
