Is there a manual to study about tazpkg, so I can find the command myself? I couldn't find one online...

http://hg.slitaz.org/tazpkg/raw-file/tip/doc/tazpkg.en.html
or open it with an editor

sorry, double post

Thanks for this link.
I don't see a way to automatically find lost files and reinstall the packages, but I'll try further...

When you say files lost do you mean tazpkgs you thought were installed but tazpkgbox the GUI version of tazpkg doesn't show them at all or as installed.

There are bugs in tazpkgbox, I don't trust what it says.

I put a new repository in for slitaz-2.0 after a recharge it showed fewer than 50 tazpkgs. The package statistics are correct,but the package display is wrong.

tazpkg on the commandline as root listed everything correctly

root@slitaz: tazpkg list

shows whats installed.

root@slitaz: tazpkg check

verify consistency of installed packages

I get alot of dependency loops, modified and lost files.

Everything works so I ignore it.

Remember, if it ain't broke don't fix it.

Some of my programs didn't work. And on the command line I saw that some programs were missing. In package manager I found out that files referring to the programs were missing. Reinstallation solved the problem.

tazpkg check shows me many lost files. How do I pipe this to a "reinstallation command"?
tazpkg check | ??? get-install --forced ???

you may want to try this:

tazpkg check | sed 'N;s/\n / /;P;D;' | grep "Files lost from" | sed -n /\ $/!p | cut -d \  -f 4 > lostfilepackages.txt

check lostfilepackages.txt content and then, if you dare

tazpkg get-install-list lostfilepackages.txt --forced

i'm not responsible of what happens :-)
if you are really crazy you can pipe the two commands with &&

I'll try the two single commands. For now I have Slitaz installed to check it out, so I'll dare...
Can you tell me, what the first command does? "tazpkg check" and "grep..." are obvious to me, but the rest...

And how do I get these code blocks?

sed 'N;s/\n / /;P;D;' has been stealed from wikipedia sed page :-) :
http://en.wikipedia.org/wiki/Sed
it removes newlines from sentences where the second sentence starts with one space. when i'll grow old i will understand how does it works ...
sed -n /\ $/!p removes lines ending with a space
cut -d \ -f 4 select the 4th field in every row using a space as separator

you can copy-paste the code, if you add a command at a time to the pipe you can check every single output

I tried the first command. It worked partially...
I only had to add another » | sed 'N;s/\n / /;P;D;'«.
Using this sed command only once, results in some lines with spaces at its end, but which contain packages with lost files.

example:
Files lost from libcdio 0.80 : [space][space]
/usr/lib/libcdio.so.7.1.1 /usr/lib/libudf.so.0.0.0

The second sed command then removes them.

So
tazpkg check | sed 'N;s/\n / /;P;D;' | sed 'N;s/\n / /;P;D;' | grep "Files lost from" | sed -n /\ $/!p | cut -d \ -f 4 > lostfilepackages.txt
and
tazpkg get-install-list lostfilepackages.txt --forced
work perfect!

i did not miss /usr/lib/libcdio.so.7.1.1 so i've tried to delete it and checked the output of tazpkg check: i don't know the reason why but the output is

Files lost from libcdio 0.80 :
  
  /usr/lib/libcdio.so.7.1.1
  target of symlink  /usr/lib/libcdio.so.7
  target of symlink  /usr/lib/libcdio.so

and not as i would expect

Files lost from libcdio 0.80 :
  /usr/lib/libcdio.so.7.1.1
  target of symlink  /usr/lib/libcdio.so.7
  target of symlink  /usr/lib/libcdio.so

The empty line is not an empty line but a line with two spaces in it, so get caught by sed 'N;s/\n / /;P;D;' and the resulting output is the one you posted.
So in my opinion it would make more sense, instead of repeating sed 'N;s/\n / /;P;D;' 2 times, delete all lines which contains just two spaces with sed '/^ $/d' before to run sed 'N;s/\n / /;P;D;' . This would catch 3 occurence of only two space lines too. Then, with the last sed, catch the lines ending with : instead the ones ending with spaces.
do you agree on this?
so the final command line could be

tazpkg check | sed '/^  $/d' | sed 'N;s/\n / /;P;D;' | grep "Files lost from" | sed '/:$/d' | cut -d \  -f 4 > lostfilepackages.txt

followed by

tazpkg get-install-list lostfilepackages.txt --forced

sure a solution of this kind depends a lot on tazpkg check output.

I'm on Ubuntu at the moment, so I will try that later, but it sounds plausible.

Yes, I agree. It works!
