Sometimes you need more than your operating system gives you.

That's when a text editor comes in handy.

#!/bin/bash
 
EXPECTED_ARGS=2
E_BADARGS=65
E_BADPATH=66
 
if [ $# -ne $EXPECTED_ARGS ]
then
  echo "Usage: `basename $0` {source} {dest}"
  exit $E_BADARGS
fi
 
if [[ ! -f "$1" ]]; then
    echo "Source file does not exist or is not a regular file."
    exit $E_BADPATH
fi
 
DESTSIZE=`du -b "$1" | awk '{print \$1; }'`
 
DESTFILENAME=`basename "$1"`
 
if [[ -d "$2" ]]; then
    DESTPATH="$2/$DESTFILENAME"
else
    DESTDIR=`dirname "$2"`
    if [[ ! -d "$DESTDIR" ]]; then
        echo "Dest dir does not exist."
        exit $E_BADPATH
    fi
    DESTPATH="$2"
fi
 
 
cat "$1" | pv -s $DESTSIZE -p -e -r > "$DESTPATH"
 
exit 0

Copying large files to my NAS becomes so much more fun when I actually KNOW that it's doing what it should. Progress bars FTW!

UPDATE: Now it's actually working for more than one case. :)

Feel free to insert quotation marks where appropriate if you want to handle file names with spaces in them. :)

Now it should work with file names with spaces and copying to folders as well. Stupid of me not to test all cases before on real data before I uploaded it. :)
