Using pv: gcp() { cat "$1" | pv | cat > "$2" }

• gcmalloc 13y ago
  useless use of cat pv < "$1" > "$2"

    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.
