[SOLVED] Slackpkg question....

linus72 · 08-10-2010, 05:08 PM

So, I need to know if there is a way to command slackpkg to reinstall
all installed packages...?

I dont think there is but also wanted to know if I could somehow
edit scripts, etc to enable this

I made a template doing

Code:

slackpkg generate-template Mini

I then tried to run it and of course it says

Quote:

All packages from Mini template are already installed

I need this because as many know here I make variations of livecd's
and I have injured one of my installs when I ran a script that I shouldn't have and it deleted several directories under /etc
usr/lib and /usr/bin
I have no idea exactly what was deleted and thus I wish to reinstall all
installed packages
There must be a way to do this without the borish method of manually reinstalling hundreds of pkgs

Is there a way to grep /var/log/packages and say reinstall all?
thx

If you are trying to reinstall all the packages...why not just reinstall Slackware? You can backup /home so your user configuration is saved (better yet, perhaps you already put /home on it's own partition).

How about...

Code:

echo "a ap d e f k kde l n t tcl x xap y" > /tmp/stuff
slackpkg reinstall /tmp/stuff

Save a line.

Code:

echo "a ap d e f k kde l n t tcl x xap y" | xargs -i slackpkg reinstall {}

EDIT: PLEASE keep in mind that I haven't tried this.

dugan, I think that your method will run slackpkg 14 times; using the actual file will only run it once.

That's a really neat trick though. I'll keep it in mind for other uses.

I may try that dugan as many of my installs are functioning retarded anyway...

I think it may work as looking at term after running it

Code:

echo "a ap d e f k kde l n t tcl x xap y" | xargs -i slackpkg reinstall {}

seems it correctly will reinstall all..except I unmarked slackpkg of course

here we go....

linus72 · 08-10-2010, 07:29 PM

OK
I ran that above and although it went thru the motions of reinstalling everything there are no .new files anywhere?
and var/cache/packages is empty of pkgs; shouldn't it be full?

EDIT:
update; it didn't actually reinstall anything and although the term showed slackpkg downloading and reinstalling everythin it didnt do anything...lol
how do I make it work for real?
or why is it not working?

If the *.new file is the same as the old one, Slackware deletes it.
Here's the code in the doinst.sh script:

Code:

config() {
  NEW="$1"
  OLD="$(dirname $NEW)/$(basename $NEW .new)"
  # If there's no config file by that name, mv it over:
  if [ ! -r $OLD ]; then
    mv $NEW $OLD
  elif [ "$(cat $OLD | md5sum)" = "$(cat $NEW | md5sum)" ]; then
    # toss the redundant copy
    rm $NEW
  fi
  # Otherwise, we leave the .new copy for the admin to consider...
}

No, by default Slackpkg automatically deletes the downloaded packages after it's done with them. You can change that by setting 'DELALL=off' in /etc/slackpkg/slackpkg.conf

linus72 · 08-10-2010, 08:01 PM

OK
then I guess it did work as some things like pkgtool which weren't working seem to be working...
this should be added to slackpkg somehow...so SOLVED I would say!
Thanks everyone/Richard/Dugan!
you guys are sub-genius!

yeah I got new mail /var/mail/root

I haven't tried this but why not do

Code:

slackpkg reinstall a ap d e f k kde l n t tcl x xap y

Instead of messing about with files and xargs? Does it work?

Yeah, no need to use xargs here.

xargs would be useful for something like:

Code:

# find all packages that end with a build number (unofficial packages
# usually end with a tag) EXCEPT for aaa_elflibs and pass them as args
# to 'slackpkg reinstall'
ls /var/log/packages/ \
  | grep '[1-9][0-9]*$' \
  | grep -v '^aaa_elflibs' \
  | rev \
  | cut -d- -f4- \
  | rev \
  | xargs slackpkg reinstall

Note: Just an example, don't really use this. The other command is better I think.

The slackpkg man page was rather vague in its explanation of PATTERN on the command line. The man page stated rather plainly that a file containing many patterns would work. I pointed the OP to a solution that I was very confident would work versus one for which I wasn't. That's all.
