FILE'S and FOLDER'S Part-2

FILES & FOLDERS PART-II

CREATING FOLDERS :
Cmd4a : Creating a single folder.

#mkdir foldername

Example :
#mkdir test

Cmd4b : Creating multiple folders at a time
#mkdir 1{1,2,3}
This command will create folders with name 11,12,13. You can see weather this folders are created or not by using ls or dir command.


Cmd4c : Creating multiple directories and sub directories at a time. This is very much advanced and very much useful command. Some times we have to create a directory structure with sub directories in it. Which are not exist before.
For example I want to create the directory structure as below
               /test
                / \
              /     \
           /           \
      user1       user2
       /  \            /  \
    /       \        /      \
 /            \    /          \
apple   goa pine     tom


So if I want to create these many folders at a time i have to execute the following commands.
First i have to create test directory, then I have to change the directory to it and the create two more directories as user1 and user2 and so on as below.
#mkdir test
#cd test
#mkdir user1
#mkdir user2
#cd user1
#mkdir apple
#mkdir goa
#cd ..
#cd user2
#mkdir pine
#mkdir tom

So you see these many commands i have to execute to create that directory structure. But in linux, its very much easy if you know this option with mkdir command. Execute the mkdir command with -p option it will create subdirectories though they didnt exist.


#mkdir -p test/{user1/{apple,goa}, user2/{pine,tom}}

Thats it you are done. This will create all the folders and sub folders.

FILES & FOLDERS PART-I

There is one saying in Linux/*nix world, that if you can play with files and folders in Unix you are almost there to become a Unix expert. So let us start our first lesson to become Unix expert by learning about files and folder operations.

CREATING FILES:


Cmd1 : Use touch command to create empty file's

to create file's

SYNTAX:

#touch filename

Example:
#touch test

To create multiple files at a time..

#touch {filename1 filename2 filename3}
#touch {1,2,3}{4,5,6}
The above command will create files with 14,15,16,24,25,26,34,35,36 as names by using this you can create n number of files at a time.
For checking weather your files/folders are created you can use ls command.

Please check linuxnix.com for updates.

Cmd2 : Creating files using cat command in combination of output redirecting operator(>)
#cat > filename
Once enter this command you have to enter the content of the file and once you finish it just press Ctrl+d this will save the file. Use again ls command to display the files created.

Cmd3 : Creating a file with any editor(either VI,emacs etc)
#vi filename
Once you execute this command the file will be opened and in order to enter any data we have to first press i to go in to insert mode. Once you type the content in to the file just press esc and :wq to save and quit the file.
