In Linux operating systems, archiving and compression are two separate terms. Archiving means creating a file containing multiple files and directories to make the copy operation much more accessible. Compression means compressing data to take up less space. In Linux, the tar command is used for archiving, and for compressing gzip or bzip2. The gzip command uses Lempel-Ziv encoding (LZ77), and...
In addition to standard permissions (read, write, and execute), there are the following special permissions: 1. SUID (setuid). It is a special permission for executable files. In Linux, an executable file has the same rights as the user who executes it. Setting the SUID bit, when executed, the file has the rights of the owner and not the owner of the file. SUID files set up with owner root are a...

There is an eternal controversy between Linux users: do we need an antivirus in Linux? In Windows, it’s clear that without an antivirus, that PC will get viruses. When the computer shuts itself down, strange windows with text that you do not understand, or tens of windows that you can not close, if emails are sent automatically, the reason can only be one: the system has a virus.
