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.
      1. pwd
      2. ls
      3. 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 ..'
