[RULE] [Fwd: Re: Disk space used by a package?]

[Jason Bechtel]

You're on the right track...

I have a script called 'accumulate' that sits in /usr/local/bin
on my systems:

#!/bin/sh

# accumulate numbers from stdin until EOF
NUM=0
TOT=0
while read VAL
do
  DIGONLY=`echo "$VAL" | sed -e 's/[^0-9]//g' -e 's/^0*//'`
  [ -n "${DIGONLY}" ] || continue
  [ "${1}" = "-v" ] && echo "$DIGONLY"
  # using 'let' instead of 'expr' seems to reduce run time by over 50%
on ~5000 entries  --jmb
  #NUM=`expr $NUM + 1`
  let "NUM += 1"
  #TOT=`expr $TOT + $DIGONLY`
  let "TOT += $DIGONLY"
  [ "${1}" = "-v" ] && echo "$TOT"
done

# echo total to stdout
if [ "${1}" = "-v" ]; then
  echo "$NUM values accumulated"
  echo "Total = $TOT"
else
  echo "$TOT"
fi

# end of accumulate


If you run your rpm queries and pipe the output to this script, it will
give you a total:

rpm -qp --qf "[%{fssizes} \n]" $rpm | accumulate

Similarly, you could pipe the output from a bunch of queries:

~/.scripts/chkrpmsize.sh | accumulate

Just remove all of the extraneous debugging output from your script so
that only the sizes are printed.

PS:  I am using bash-2.05b-6mdk.
