Total size of installed packages - script

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.

Re: Total size of installed packages - script

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!

Re: Total size of installed packages - script

Yeah this is good tune.
I'm really happy of that there is somebody who takes interest in it.

But I don't know how to speed up the script. Is slowness pacman or script cause? Maybe use of tupac can speed up script. On the other hand perhaps nobody run script quickly times over

And I'm sorry for my english, if it is horrible
