Step 4: How to Test a RAR File in Linux
To test an integrity of a archive file, use option unrar t. The below command will perform a complete integrity check for each file and displays the status of the file.
unrar t tecmint.rar UNRAR 4.20 beta 3 freeware Copyright (c) 1993-2012 Alexander Roshal Testing archive tecmint.rar Testing tecmint/index.php OK Testing tecmint/index.html OK Testing tecmint/xyz.txt OK Testing tecmint/abc.txt OK Testing default/index.php OK Testing default/index.html OK Testing include/abc.txt OK Testing php/xyz.txt OK All OK
The unrar command is used to extract, list or test archive files only. It has no any option for creating RAR files under Linux. So, here we need to install RAR command-line utility to create archive files.
Step 5: How to Install Rar in Linux

# sudo apt-get install rar # sudo dnf install rar # yum install rar
