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:  column --columns
   6 why:   renamed to --output-width
   7 since: v2.30
   8
   9 --------------------------
  10
  11 what:  hwclock --compare
  12 why:   Output printed by --compare option was nonesense.
  13
  14 --------------------------
  15
  16 what:  tailf
  17 why:   "tail -f" is better nowadays, tailf has unfixed bugs
  18
  19 --------------------------
  20
  21 what:  sfdisk --show-size
  22 why:   this does not belong to fdisk, use "blockdev --getsz"
  23
  24 --------------------------
  25
  26 what:   sfdisk --Linux
  27 why:    unnecessary option, only Linux (non-DOS mode) is supported
  28
  29 --------------------------
  30
  31 what:   sfdisk --unit
  32 why:    unnecessary option, only 'S'ector unit is supported
  33
  34 --------------------------
  35
  36 what:   sfdisk --show-pt-geometry
  37 why:    equal to --show-geometry for a long time
  38
  39 --------------------------
  40
  41 what:  "swapon --summary" output format
  42 why:   does not provide control on output data formatting. The recommended solution
  43        is to use --show=<columns> in all scripts.
  44
  45 --------------------------
  46
  47 What:   mkfs
  48 Why:    use filesystem specific mkfs.<type>.
  49
  50 --------------------------
  51
  52 What:   fdisk -s <device>
  53 Why:    this does not belong to fdisk, use "blockdev --getsz"
  54
  55 --------------------------
  56
  57 What:   'udev' and 'list' blkid(8) output formats
  58 Why:    udevd links libblkid directly; the 'list' is unnecessary, use lsblk(8)
  59
  60 --------------------------
  61
  62 What:   line(1) command
  63 Why:    useless, nobody uses this command, head(1) is better
  64
  65 --------------------------
  66
  67 What:   pg(1) command
  68 Why:    use less(1) or more(1)
  69
  70 --------------------------
  71
  72 What:   CHS stuff in fdisk (except SUN where are partitions addresses by cylinders only)
  73 Why:    use addresssing by sectors, CHS does not work with modern disks,
  74         confusing for users...
  75
  76 --------------------------
  77
  78 What:   losetup -s
  79 Why:    the option -s is in collision with the Loop-AES losetup dialect that is used
  80         in some distributions. Use the long version (--show) only.
  81
  82 --------------------------
  83
  84 What:   losetup output format without --list
  85
  86         deprecated format"
  87
  88           # losetup -a
  89           /dev/loop0: []: (/home/fs-images/swap.img)
  90           /dev/loop1: []: (/home/fs-images/disk.img), offset 100
  91
  92         new format:
  93
  94           # losetup
  95           NAME       SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE
  96           /dev/loop0         0      0         0  0 /home/fs-images/swap.img
  97           /dev/loop1         0    100         0  0 /home/fs-images/disk.img
  98
  99 --------------------------
 100
 101 What:   tunelp
 102 Why:    parallel port printers are probably almost extinct devices
 103
 104 ----------------------------
 105
