The following is a list of commands or features that are deprecated. All deprecated utils are in maintenance mode and we keep them in source tree for backward compatibility only. what: column --table-empty-lines why: renamed to --keep-empty-lines since: v2.37 -------------------------- what: hwclock --debug why: renamed to --verbose, and may be repurposed later. since: v2.32 -------------------------- what: hwclock -v for version why: renamed to -V since: v2.20 (was repurposed to verbose in v2.32) -------------------------- what: column --columns why: renamed to --output-width since: v2.30 -------------------------- what: sfdisk --show-size why: this does not belong to fdisk, use "blockdev --getsz" -------------------------- what: sfdisk --Linux why: unnecessary option, only Linux (non-DOS mode) is supported -------------------------- what: sfdisk --unit why: unnecessary option, only 'S'ector unit is supported -------------------------- what: sfdisk --show-pt-geometry why: equal to --show-geometry for a long time -------------------------- what: "swapon --summary" output format why: does not provide control on output data formatting. The recommended solution is to use --show=<columns> in all scripts. -------------------------- What: mkfs Why: use filesystem specific mkfs.<type>. -------------------------- What: fdisk -s <device> Why: this does not belong to fdisk, use "blockdev --getsz" -------------------------- What: 'udev' and 'list' blkid(8) output formats Why: udevd links libblkid directly; the 'list' is unnecessary, use lsblk(8) -------------------------- What: line(1) command Why: use the read(1) command -------------------------- What: pg(1) command Why: use less(1) or more(1) -------------------------- What: CHS stuff in fdisk (except SUN where are partitions addresses by cylinders only) Why: use addressing by sectors, CHS does not work with modern disks, confusing for users... -------------------------- What: losetup -s Why: the option -s is in collision with the Loop-AES losetup dialect that is used in some distributions. Use the long version (--show) only. -------------------------- What: losetup output format without --list deprecated format: # losetup -a /dev/loop0: []: (/home/fs-images/swap.img) /dev/loop1: []: (/home/fs-images/disk.img), offset 100 new format: # losetup NAME SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE /dev/loop0 0 0 0 0 /home/fs-images/swap.img /dev/loop1 0 100 0 0 /home/fs-images/disk.img -------------------------- What: tunelp Why: parallel port printers are probably almost extinct devices ---------------------------- The Single UNIX(TM) Specification, Version 2 Copyright (C) 1997 The Open Group Legacy utilities which are part util-linux package are: col line pg http://pubs.opengroup.org/onlinepubs/7908799/xcu/intro.html#tag_001_003_003
