useless use of cat pv < "$1" > "$2"

• nitrogen 13y ago
  Even if the cat at the beginning of a pipe isn't strictly necessary, it still helps readability to have everything flowing from left to right.

    I also advocate this "useless" use of cat, but you can write the redirection before the command: <"$1" pv >"$2"

    The bigger problem is that using cat destroys the file size information.
• nilved 13y ago
  pv reads content from a file by default, so that can actually be reduced further to: pv "$1" > "$2"

    Which will actually give better results this way, since it'll read the size of the file and use that to provide an estimate even.
