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: tailf
why: "tail -f" is better nowadays, tailf has unfixed bugs
--------------------------
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: "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: "pid" as binary name for "kill --pid"
why: too ugly, too obscure
--------------------------
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: useless, nobody uses this command, head(1) is better
--------------------------
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 addresssing 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
----------------------------
What: reset
Why: ncurses has better reset(1)
