Filesystem doesn't matter.

Just:

Code:

#!/bin/bash
DIR=/home/username
# du outputs "blocks folder" so we read both and just ignore the folder.
read USED_K FOLDER <<<$(du -s -B 1024 "$DIR" 2> /dev/null)
# du outputs a header line, then "filesystem blocks used available ..."
# so we ignore the header line with 'tail', then read the first three.
read FILESYSTEM TOTAL_K G <<<$(df -B 1024 "$DIR" | tail -n 1)
echo "$DIR uses $(( (USED_K*100) / TOTAL_K ))% of $FILESYSTEM"

Running this gets me

Code:

/home/username uses 51% of /dev/sdc5

write a script that will calculate amountof internal fragmentation forall files in directory. assume each block is1024 bytes

Which do you want? The space used, or something nebulous about fragmentation?

YAPPS(1)						      General Commands Manual							  YAPPS(1)

NAME

       yapps - create a Python module from a grammar file

SYNOPSIS

       yapps [ --dump ] [ --use-devel-grammar ] [ -fcontext-insensitive-scanner ] [ -p	pid ] [ -f ] input.g [ output.py ]  name

DESCRIPTION

	 --dump 			  Dump out grammar information
	   --use-devel-grammar		     Use the devel grammar parser from	    yapps_grammar.py instead of the stable grammar from grammar.py
	      -fcontext-insensitive-scanner    Scan all tokens (see docs)

       yapps generates a Python program which will parse a given grammar.

OPTIONS

       --dump Dump the grammar information to stdout.

       --use-devel-grammar
	      Use the grammar file in ./yapps_grammar.py instead of yapps/grammar.py.
	      This option is useful for testing new grammar parsers. (Yes, yapps' parser is itself written with yapps...)

       -fcontext-insensitive-scanner
	      Set the option to use the non-context-sensitive scanner.

CAVEATS

       yapps implements a recursive-descent scanner.

HISTORY

       Written by Amit J. Patel <amitp@cs.stanford.edu>.
       This version was enhanced by Matthias Urlichs <smurf@debian.org>.  It is not downwards-compatible with the original yapps2 (yet) and uses a
       different runtime library.
       See the change log for details.
