Please note that the ddate, fastboot, fasthalt, halt, initctl, ramsize, rdev, reboot, rootflags, shutdown, simpleinit and vidmode tools have been removed from util-linux since 2012. Please note that the ‘arch’ tool has been replaced with the ‘uname’ or ‘arch’ tools from the coreutils package, the ‘elvtune’ is obsolete since Linux kernel 2.6.9, and the ‘tunelp’ tool is deprecated.
Supported operating systems and availability
Despite the fact that it includes so many command-line utilities, the util-linux project is distributed as a single sources archive of approximately 4 MB in size. This package is an essential component of a GNU/Linux system and it is usually installed by default on any distribution of Linux, supporting both 32-bit and 64-bit instruction set architectures.
