6. Create multiple rar files

To compress say ‘file1′, ‘file2′ and ‘file3′ simultaneously, use below command

# rar a file1.rar file1 file2 file3

You can also use the following method to RAR multiple files.

# rar a -r file1.rar file1 file2 file3

7. Set password for RAR file

While archiving, you can set a password (using -p option). If you omit the password on the command line, you will be prompted with a message “enter password” and the password is case sensitive.

# rar a -pQAZWSXEDC archive.rar /var/log/

or

# rar a -p archive.rar /var/log/

Enter password (will not be echoed):
