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:   chkdupexe
   6 Why:    unnecessary, in Perl, not used in distributions, possible to replace
   7         by a simple shell script.
   8
   9 --------------------------
  10
  11 What:   'udev' and 'list' blkid(8) output formats
  12 Why:    udevd links libblkid directly; the 'list' is unnecessary, use lsblk(8)
  13
  14 --------------------------
  15
  16 What:   line(1) command
  17 Why:    useless, nobody uses this command, head(1) is better
  18
  19 --------------------------
  20
  21 What:   pg(1) command
  22 Why:    use less(1) or more(1)
  23
  24 --------------------------
  25
  26 What:   CHS stuff in fdisk (except SUN where are partitions addresses by cylinders only)
  27 Why:    use addresssing by sectors, CHS does not work with modern disks,
  28         confusing for users...
  29
  30 --------------------------
  31
  32 What:   losetup -s
  33 Why:    the option -s is in collision with the Loop-AES losetup dialect that is used
  34         in some distributions. Use the long version (--show) only.
  35
  36 --------------------------
  37
  38 What:   losetup output format without --list
  39
  40         deprecated format"
  41
  42           # losetup -a
  43           /dev/loop0: []: (/home/fs-images/swap.img)
  44           /dev/loop1: []: (/home/fs-images/disk.img), offset 100
  45
  46         new format:
  47
  48           # losetup
  49           NAME       SIZELIMIT OFFSET AUTOCLEAR RO BACK-FILE
  50           /dev/loop0         0      0         0  0 /home/fs-images/swap.img
  51           /dev/loop1         0    100         0  0 /home/fs-images/disk.img
  52
  53 --------------------------
  54
  55 What:   tunelp
  56 Why:    parallel port printers are probably almost extinct devices
  57
  58 --------------------------
  59
  60 What:   elvtune
  61 Why:    useless for kernel >= 2.6.9
  62
  63 ---------------------------
  64
  65 What:   arch(1) command
  66 Why:    deprecated in favor of uname(1) or arch(1) from coreutils
  67
  68         The arch(1) has been added (during 2.13 development cycle) to coreutils
  69         where it will be maintained as an alias for uname(1) command.
  70
  71 ----------------------------
  72
  73 What:   last(1)
  74 Why:    nobody uses this implementation
  75
