Give some commands of LINUX operating system?

  1. Just press 'Shift+TAB' button on your keyboard. You'll get all commands
  2. cd
    Change directory. This is the command you use to change into different directories. An example would be "cd /mnt" (minus the quotes, always minus the quotes) now you will be the /mnt dir.

    mount
    Mounts a filesystem. ex, "mount /dev/hda4 /mnt" mounts hard drive partition 4 in your /mnt directory.

    cp
    Copies files. eg, "cp SomeFile /home/momo/" copies a SomeFile into user momo's home directory.

    mv
    Move. Does the same as cp except moves the file instead of copying it. You also use the mv command to rename files/directories ex, "mv file1 SomeNewFilename" renames file1 to SomeNewFilename.

    mkdir
    Make Directory. ex, "mkdir /home/momo/new" creates a directory named new in momo's home directory. If you are currently in the directory you want to make the the new directory in you can just do "mkdir new" to make a directory named "new".

    rm
    Removes files and directories. ex, "rm file1". To use rm without a hassle you may want to use "rm -rf". This way you won't be prompted to confirm the removal of the file. You can not use rm to remove directories which are not empty unless you use an option telling rm to do otherwise, the -rf option works well for this. Use "rm -rf" carefully ;-).

    rmdir
    Removes empty directories. ex, "rmdir new".

    man
    displays the man page for a paticular application or command. ex, "man rm". Man is your friend, please use it :-) .
