Checking disk quota on multi-user system

[Antagony]

At my university we get a linux account with 75 megs of disk space. I was looking through the "df" manpage and I realize I need to use some other command to figure out how much of my quota I have left to use.

Anyone know how I could do this? Perhaps I need to write a script?

Or as an alternative, how could I manipulate the "ls" command to show me how much disk space I've used under my home directory?

It's some flavor of Redhat 7 if that helps any. Thanks for reading my dumb post.

if all your files are in one directory you could just do a simple 'du -sh [directory_name]' for example if the only directory you files in is ~/ then du -sh ~/

s is for summary(otherwise each file name gets printed)
and h for human readable ie meg gig

heh i got bored so heres one for you if you have files scattered all over the system, use with caution or your sys admin will hate you (youll understand when you look at the code)

#!/bin/sh

FILES=`find / -user $1 2>/dev/null`
SIZE=0
for i in ${FILES}
do
    TMP=`du ${i}|cut -f 1 2>/dev/null`
    if [ ! $? -eq 1 ]; then
        let "SIZE=${SIZE}+${TMP}" 2>/dev/null
    fi
done
PERCENT=`bc << EOF
(${SIZE} * 100) / 76800
EOF`
echo "Quota size is ${SIZE}k using ${PERCENT}%"

not perfect but whatever
