Most Unix systems use fortunes which are slanted heavily toward the user base of Unix, and thus contain many obscure jokes about computer science and computer programming. Other favoured sources include quotations from science fiction ( Star Trek , The Cyberiad , Doctor Who , The Hitchhiker's Guide to the Galaxy , etc.), Zippy the Pinhead , and ...

A Linux distribution [a] (often abbreviated as distro) is an operating system that includes the Linux kernel for its kernel functionality. Although the name does not imply product distribution per se, a distro, if distributed on its own, is often obtained via a website intended specifically for the purpose.
The table below shows the default file system, but many Linux distributions support some or all of ext2, ext3, ext4, Btrfs, ReiserFS, Reiser4, JFS, XFS, GFS2, OCFS2, and NILFS. It is possible to install Linux onto most of these file systems. The ext file systems, namely ext2, ext3, and ext4 are based on the original Linux file system.
Most Linux distributions are descended from other distributions, most being traceable back to Debian, Red Hat or Softlanding Linux System (see image right). Since most of the content of a distribution is free and open source software, ideas and software interchange freely as is useful to the individual distribution. Merges (e.g., United Linux ...
Linux distributions generally do not include a Unix compatible version of the crypt command. This is largely due to a combination of three major factors: crypt is relatively obscure and rarely used for e-mail attachments nor as a file format
While xz is commonly present in most Linux distributions, at the time of discovery the backdoored version had not yet been widely deployed to production systems, but was present in development versions of major distributions. [6] The backdoor was discovered by the software developer Andres Freund, who announced his findings on 29 March 2024. [7]
In Linux, if the script was executed by a regular user, the shell would attempt to execute the command rm -rf / as a regular user, and the command would fail. However, if the script was executed by the root user, then the command would likely succeed and the filesystem would be erased.
