Documentation/deprecated.txt

   1 The following is a list of commands or features that are deprecated.  All
   2 deprecated utils are in maintenance mode and we keep them in source tree for
   3 backward compatibility only.
   4
   5 what:  hwclock --debug
   6 why:   renamed to --verbose, and may be repurposed later.
   7 since: v2.32
   8
   9 --------------------------
  10
  11 what:  hwclock -v for version
  12 why:   renamed to -V
  13 since: v2.20 (was repurposed to verbose in v2.32)
  14
  15 --------------------------
  16
  17 what:  column --columns
  18 why:   renamed to --output-width
  19 since: v2.30
  20
  21 --------------------------
  22
  23 what:  sfdisk --show-size
  24 why:   this does not belong to fdisk, use "blockdev --getsz"
  25
  26 --------------------------
  27
  28 what:   sfdisk --Linux
  29 why:    unnecessary option, only Linux (non-DOS mode) is supported
  30
  31 --------------------------
  32
  33 what:   sfdisk --unit
  34 why:    unnecessary option, only 'S'ector unit is supported
  35
  36 --------------------------
  37
  38 what:   sfdisk --show-pt-geometry
  39 why:    equal to --show-geometry for a long time
  40
  41 --------------------------
  42
  43 what:  "swapon --summary" output format
  44 why:   does not provide control on output data formatting. The recommended solution
  45        is to use --show=<columns> in all scripts.
  46
  47 --------------------------
  48
  49 What:   mkfs
  50 Why:    use filesystem specific mkfs.<type>.
  51
  52 --------------------------
  53
  54 What:   fdisk -s <device>
  55 Why:    this does not belong to fdisk, use "blockdev --getsz"
  56
  57 --------------------------
  58
  59 What:   'udev' and 'list' blkid(8) output formats
  60 Why:    udevd links libblkid directly; the 'list' is unnecessary, use lsblk(8)
  61
  62 --------------------------
  63
  64 What:   line(1) command
  65 Why:    use the read(1) command
  66
  67 --------------------------
  68
  69 What:   pg(1) command
  70 Why:    use less(1) or more(1)
  71
  72 --------------------------
  73
  74 What:   CHS stuff in fdisk (except SUN where are partitions addresses by cylinders only)
  75 Why:    use addressing by sectors, CHS does not work with modern disks,
  76         confusing for users...
  77
  78 --------------------------
  79
  80 What:   losetup -s
  81 Why:    the option -s is in collision with the Loop-AES losetup dialect that is used
  82         in some distributions. Use the long version (--show) only.
  83
  84 --------------------------
  85
  86 What:   losetup output format without --list
  87
  88         deprecated format"
  89
  90           # losetup -a
  91           /dev/loop0: []: (/home/fs-images/swap.img)
  92           /dev/loop1: []: (/home/fs-images/disk.img), offset 100
  93
  94         new format:
  95
  96           # losetup
  97           NAME       SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE
  98           /dev/loop0         0      0         0  0 /home/fs-images/swap.img
  99           /dev/loop1         0    100         0  0 /home/fs-images/disk.img
 100
 101 --------------------------
 102
 103 What:   tunelp
 104 Why:    parallel port printers are probably almost extinct devices
