How To Find Memory Occupied By Installed *.ipk

[grog]

Hi again. You made some good suggestions in you last post, thanks. Those and the output your 'ipkg-files file' made me realize what the problem might be. The version of ipkg that is used in OZ doesn't return directory names, just file names, whereas it seems the one in the sharp rom returns everything. And while directories & symlinks themselves do take up space, that's negligable compared to the files, so I've tweaked the script a bit to take this into account. As well, I discovered another potential problem depending on what directory you're in at the time the script is run, so I've fixed that too.

Try out the latest version & let me know how it goes. This copy won't spit out the debugging output, so if it still doesn't work (cross our fingers), uncomment the TESTING line & attach the output. thks

Hi grog,

Seems you attached the wrong script - there're no changes compared to previous one.

oops. Here here's the new one.

Unfortunately no luck  
 
Nearly the same debug output as before and failed on the same line:
/home/QtPalmtop/bin/ipkg-size: arith: syntax error: "TOTALSIZE+224"

224 is the first echo - size of /

Ok, I don't know what I may have been imbidding to much of yesterday, but I *still* gave you the wrong version of the script. Here's the right one. Give'er another go. haveAhappy

No echos for a folders now but still for a links.
Unfortunately again it stopped on "TOTALSIZE=$((TOTALSIZE+$line))" line.
I believe something wrong with syntax here.

Shouldn't be a problem. Like I said before, directories & links on a unix filesystem are still just special files that take up space, albeit a small amount compared to other 'regular' files.

Unfortunately again it stopped on "TOTALSIZE=$((TOTALSIZE+$line))" line.

The syntax is correct for all modern bourne- & korn-based shells I'm aware of, which includes the version of sh provided by busybox, but let's see. What's the exact output of these commands on your Z?

Code: [Select]

root@grond[~]# N=4
root@grond[~]# T=$((T+N))
root@grond[~]# echo $N $T
4 4
root@grond[~]# T=$((T+N))
root@grond[~]# echo $N $T
4 8
root@grond[~]# T=$((T+N))
root@grond[~]# echo $N $T
4 12There's another way the math can be done, using a utility called bc. See if you can find a package that's installable on your Z (search elsi if necessary) & depending on your output of the above commands & that I'll make another mod & see if that'll make a difference.

Yes I agree with you. I just thought this could be the cause of error.

root@grond[~]# echo $N $T
4 8
root@grond[~]# T=$((T+N))
root@grond[~]# echo $N $T
4 12

Here is the error!!!
If I typed this in my default shell (/bin/bash) I got the same output as you.
But if I first typed:
/usr/bin/env sh

and after switched to the shell environment typed:

$ N=4
$ T=$((T+N))

the error returned:

arith: syntax error: "T+N"

I dodn't know in which shell I went after "/usr/bin/env sh" but after I have changed in your script the first line to the "/bin/bash" everything start to work and I found that my file.ipkg has installed size 966kb  

Thank you grog for your time and the nice script

kewl. I figured it wa a shell problem. The sharp rom must come with an older version of busybox that doesn't have emulation for integer math calculation. It's good that you had bash so you could figure that out.

FYI, you could have changed the '/usr/bin/env sh' to '/usr/bin/env bash' & it would have worked as well (that convention works even if bash wasn't installed under /usr/bin, as it searches your path. That's why I use it.).

Thank you grog for your time and the nice script  [div align=\"right\"][a href=\"index.php?act=findpost&pid=84498\"][{POST_SNAPBACK}][/a][/div]

I'm just glad that by working together we managed to finally figure it out.

Thanks for you help in improving my script .
havefun!!
