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
   6 what: "swapon --summary" output format
   7 why:  does not provide control on output data formatting. The recommended solution
   8       is to use --show=<columns> in all scripts.
   9
  10 what: "pid" as binary name for "kill --pid"
  11 why:   too ugly, too obscure
  12
  13 --------------------------
  14
  15 What:   mkfs
  16 Why:    use filesystem specific mkfs.<type>.
  17
  18 --------------------------
  19
  20 What:   fdisk -s <device>
  21 Why:    this does not belong to fdisk, use "blockdev --getsz"
  22
  23 --------------------------
  24
  25 What:   'udev' and 'list' blkid(8) output formats
  26 Why:    udevd links libblkid directly; the 'list' is unnecessary, use lsblk(8)
  27
  28 --------------------------
  29
  30 What:   line(1) command
  31 Why:    useless, nobody uses this command, head(1) is better
  32
  33 --------------------------
  34
  35 What:   pg(1) command
  36 Why:    use less(1) or more(1)
  37
  38 --------------------------
  39
  40 What:   CHS stuff in fdisk (except SUN where are partitions addresses by cylinders only)
  41 Why:    use addresssing by sectors, CHS does not work with modern disks,
  42         confusing for users...
  43
  44 --------------------------
  45
  46 What:   losetup -s
  47 Why:    the option -s is in collision with the Loop-AES losetup dialect that is used
  48         in some distributions. Use the long version (--show) only.
  49
  50 --------------------------
  51
  52 What:   losetup output format without --list
  53
  54         deprecated format"
  55
  56           # losetup -a
  57           /dev/loop0: []: (/home/fs-images/swap.img)
  58           /dev/loop1: []: (/home/fs-images/disk.img), offset 100
  59
  60         new format:
  61
  62           # losetup
  63           NAME       SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE
  64           /dev/loop0         0      0         0  0 /home/fs-images/swap.img
  65           /dev/loop1         0    100         0  0 /home/fs-images/disk.img
  66
  67 --------------------------
  68
  69 What:   tunelp
  70 Why:    parallel port printers are probably almost extinct devices
  71
  72 --------------------------
  73
  74 What:   deprecated_last(1)
  75 Why:    nobody uses this implementation
  76
