Important arguments

Long - arguments typically occur only in the GNU version.

  • -a shows all files.
  • - apparent -size displays visible size ( at a very small text file the actual bytes instead of the size on the file system)
  • -b shows the file size in kilobytes rather than in bytes. (GNU - specific)
  • -c shows the end of the output to the total size.
  • -h shows the sizes of " human-readable ", ie, in megabytes, gigabytes ... sometimes held in very high numbers in kilobytes.
  • -s displays only the sum of all file sizes, rather than the individual elements.
  • - si uses SI sizes ( A kilobyte = 1000 bytes ), so KiB, MiB ...
  • - time indicates the time of the last change.
