Full Discussion: calculate internal fragmentation in directory
Homework and Emergencies Emergency UNIX and Linux Support calculate internal fragmentation in directory Post 302580113 by Corona688 on Wednesday 7th of December 2011 02:31:15 PM

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

NAME

       page_util_quote - page character quoting utilities

SYNOPSIS

       package require page::util::quote  ?0.1?

       package require snit

       ::page::util::quote::unquote char

       ::page::util::quote::quote'tcl char

       ::page::util::quote::quote'tclstr char

       ::page::util::quote::quote'tclcom char

_________________________________________________________________

DESCRIPTION

       This package provides a few utility commands to convert characters into various forms.

API

       ::page::util::quote::unquote char
	      A  character,  as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
	      their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the  result
	      of the command.

       ::page::util::quote::quote'tcl char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
	      regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.

       ::page::util::quote::quote'tclstr char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl  parser  and
	      will generate a human readable representation of the character in question.  The string is returned as the result of this command.

	      The  string  does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
	      with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.

       ::page::util::quote::quote'tclcom char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser  when
	      used within a Tcl comment. The string is returned as the result of this command.

       This  document,	will  undoubtedly  contain  bugs  and  other  problems.  Please report such in the category page of the Tcllib SF Trackers
