deprecated

Guest on 2nd May 2022 01:38:47 AM

  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
  105.
