1.locate

    You can use this command to find a file, just like the windows search in Windows.in addition to that, using the -i argument along with this command will make it case-insensitive, so you can search for a file even if you don’t know its exact name.

To search for a file that having more than two words, use an asterisk *. For ex, locate -i scnotes* note command will search for any file that contains the word “scnote” and “scnote”, even if it is in uppercase or lowercase.

2.find

    It is similar to the locate command, using find it also  searches for files and directories. The difference between locate and find commands is that, you use the find command to find the files within a specific directory.

As an example, find /home/ -name scnotes.txt command will search for a file called scnotes.txt within the home directory and its subdirectories.

3.grep

This is another basic Linux command that is very helpful for everyday use .It lets you search through all the text in a given file.

For example if you type “grep pink colors.txt” it will search for the word pink in the colors file. Lines that contain the word will be shown fully.

4.df

    df command is used to get a report on the system’s disk space usage, shown in percentage and KBs. If you want to see the disk space usage report in megabytes, type df -m.

5.du

    If you want to check the size of a file or a directory, the du (Disk Usage) command is used for that purpose.However, the disk usage summary will show disk- block numbers instead of the usual size format. If you want it to show it in bytes, kilobytes, and megabytes, add the -h argument to the command.

6.tar

    The tar command is one of the most used commands to archive multiple files into a tarball file ,a common Linux file format that is like zip format in other operating systems, with compression being optional.

This command has a long list of functions such as adding new files into an existing tarball file, listing the total  content of an archive, extracting the content from a file, and many more.

7.chmod

    chmod is another Linux command, used to change the write,read and execute permissions of files and directories.

8.ping

9.history

     History command is used to show the previously typed command in the terminal 

10.echo
