Total size of installed packages - script

Question

Hi,
I spend few hours today to make bash script, that allow me get total size of installed packages on my disk. It may be useful for many users.
Here it is:
#!/bin/bash
total=0
progress="-"
count=`pacman -Q | wc -l`
echo "Reading info of "$count" packages reported by 'pacman -Q'.
This may take few minutes..."
for pkg in `pacman -Q | sed 's/\ .*//'`
do
s=`pacman -Qi $pkg | sed -e '/Installed\ Size/!d; s/Installed\ Size\ :[\ ]*//; s/\ K//; s/,/./'`
if [ "$s" != "" ]; then
total=`echo $total" + "$s | bc`
printf "\033[1D"$progress
if [ "$progress" == "|" ]; then progress="-"; fi;
if [ "$progress" == "\\" ]; then progress="|"; fi;
if [ "$progress" == "_" ]; then progress="\\"; fi;
if [ "$progress" == "/" ]; then progress="_"; fi;
if [ "$progress" == "-" ]; then progress="/"; fi;
fi
done
echo
echo "Total size of installed packages is "$total" K"
! Script requere bc command (pacman -S bc) !
Thank you for corrections and comments.

I added a crude human-readability block near the end.
#!/bin/bash
total=0
progress="-"
count=`pacman -Q | wc -l`
echo "Reading info of "$count" packages reported by 'pacman -Q'.
This may take few minutes..."
for pkg in `pacman -Q | sed 's/\ .*//'`
do
s=`pacman -Qi $pkg | sed -e '/Installed\ Size/!d; s/Installed\ Size\ :\ *//; s/\ K//; s/,/./'`
if [ "$s" != "" ]; then
total=`echo $total" + "$s | bc`
printf "\033[1D"$progress
if [ "$progress" == "|" ]; then progress="-"; fi;
if [ "$progress" == "\\" ]; then progress="|"; fi;
if [ "$progress" == "_" ]; then progress="\\"; fi;
if [ "$progress" == "/" ]; then progress="_"; fi;
if [ "$progress" == "-" ]; then progress="/"; fi;
fi
done
suffix='K'
if [ `echo "$total > 1024" | bc` = 1 ]; then
total=`echo "scale=2; $total / 1024" | bc`
suffix='M'
if [ `echo "$total > 1024" | bc` = 1 ]; then
total=`echo "scale=2; $total / 1024" | bc`
suffix='G'
fi
fi
echo
echo "Total size of installed packages is $total $suffix"
And here's a version with a simpler and more informative progress meter:
#!/bin/bash
total=0
progress="1"
count=`pacman -Q | wc -l`
echo "Reading info of "$count" packages reported by 'pacman -Q'.
This may take few minutes..."
for pkg in `pacman -Q | sed 's/\ .*//'`
do
printf "\rprocessing file "$(( progress++ ))"..."
s=`pacman -Qi $pkg | sed -e '/Installed\ Size/!d; s/Installed\ Size\ :\ *//; s/\ K//; s/,/./'`
if [ "$s" != "" ]; then
total=`echo $total" + "$s | bc`
fi
done
suffix='K'
if [ `echo "$total > 1024" | bc` = 1 ]; then
total=`echo "scale=2; $total / 1024" | bc`
suffix='M'
if [ `echo "$total > 1024" | bc` = 1 ]; then
total=`echo "scale=2; $total / 1024" | bc`
suffix='G'
fi
fi
echo
echo "Total size of installed packages is $total $suffix"
It works, good job. I didn't know about bc!
Oh, and welcome to the Arch BBS!
