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 --columns
|
|
why: renamed to --output-width
|
|
since: v2.30
|
|
|
|
--------------------------
|
|
|
|
what: hwclock --compare
|
|
why: Output printed by --compare option was nonesense.
|
|
|
|
--------------------------
|
|
|
|
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: 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: 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)
|
