APT front ends can list the dependencies of packages being installed or upgraded, ask the administrator if packages recommended or suggested by newly installed packages should be installed too, automatically install dependencies and perform other operations on the system such as removing obsolete files and packages.
aptitude is a front end to APT, the Debian package manager. [4] It displays a list of software packages and allows the user to interactively pick packages to install or remove. It has a search system utilizing flexible search patterns. It was initially created for Debian, but has appeared in RPM-based distributions as well.
The Yellowdog Updater Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager. [4] Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality.
dpkg (Debian Package) itself is a low-level tool. APT (Advanced Package Tool), a higher-level tool, is more commonly used than dpkg as it can fetch packages from remote locations and deal with complex package relations, such as dependency resolution. Frontends for APT, like aptitude and synaptic , are used for their friendlier interfaces.
Nginx is free and open-source software, released under the terms of the 2-clause BSD license. A large fraction of web servers use Nginx, [10] often as a load balancer. [11] A company of the same name was founded in 2011 to provide support and NGINX Plus paid software. [12] In March 2019, the company was acquired by F5 for $670 million. [13]
It is also capable of automatically installing the generated packages, and can try to convert the installation scripts included in the archive as well. Automatic installation should be used with caution since Linux distributions may vary significantly from one another, and using install scripts automatically converted from an Alien format may ...
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. It is recommended to use sudo on a per-command basis instead.
Inherited from the design of Nix, most of the content of the package manager is kept in a directory /gnu/store where only the Guix daemon has write-access. This is achieved via specialised bind mounts, where the Store as a file system is mounted read only, prohibiting interference even from the root user, while the Guix daemon remounts the Store as read/writable in its own private namespace.
