Handling Folders and Files with Linux command Line[part2]
In the previous part I just explained 3 commands that will help you to navigate through files and folders in your system.In this section let us discuss how to perform some actions like create, rename, remove folders using command line.
Creating a folder using the command:
The command used to create a folder is mkdir .Open up the terminal and type :
mkdir myfolder
A new folder named myfolder will be there in your home directory.You can make folders anywhere in your system.But you must mention the directory address for your folder with folder name otherwise the folder will be created in the current directory.
Eg: to make a folder in the directory /tmp use the following command.
mkdir /tmp/myfolder
Extra note : Normally your system will not display any message after creation of the folder. If you add the parameter -v to the mkdir command you will get a message after the creation of the folder (eg: mkdir myfolder -v)
Removing a file or folder
The Linux kernel consider folder and file as same .You can remove any file or folder using the command rm .
the usage of the command is rm [option] <file> .
Here are the important options you might use.
-f (forcefully removes file with no prompting)
-v (Explains what is being done)
-r (Removes files recursively in a directory.It is used when the folder contains subfolders.)
I just mentioned the syntax above. But you need just a single command to remove a folder that is
rm -rf /tmp/myfolder
here '-rf' is the option with the command which says that files will be removed recursively and forcefully. And /tmp/myfolder will be the folder we want to delete.

Handling Folders and Files with Linux command Line[part1]
As
we know Linux command Line is the powerful tool for a user. First of all let us discuss about 3 basic commands which helps you to manage files and folders.
- pwd
- ls
- cd
pwd
:
This command prints the
present working directory. That is if you want to know actual
location where you are standing in your terminal section ,just type
pwd . It makes your navigation better.
ls :
The
ls command is used to list the files and folders in the current
directory .It is similar to the 'dir' command in Windows. It is
important to mention about some parameters those are used along with
ls to make this mapping efficient .
1.
ls -a
The
above command will list all the files and folders including the
hidden
files.
2. ls -r
This
command will list the contents in reverse order.
3. ls *.txt
This
will list all the files of type .txt .You can change the extension
say .jpeg
for picture type files.
cd
:
The simple command which is used to navigate to another directory
expanded as change directory. The syntax is cd <directory>
eg:
cd /usr/bin will move the current directory to /usr/bin.
Note : You can navigate to
the previous directory by the command 'cd ..'Monday, 16 January 2012
Know the amount of available Disk Space in Linux
We are already
know that the Linux shell is the powerful tool which is capable of
doing any jobs related with Linux OS .Read more about Linux terminalclick here .Here in this
post I am going to tell about a simple command which is used to know
the free space available in the hard disk partitions with in no time.
To get started open up the terminal and :
- Type df you can see the list of partitions with available free space listed.
- Type df -a to get a detailed listing of free space. this Include in the listing file-systems that have a size of 0 blocks, which are omitted by default.
- Type df -h to get a listing more optimized .Here size is listed in MBs .-h stands for human readable form .
To get the detailed syntax information
use the command man df. This
will list all the possibilities of the command.
