UExtract-4.14 - A Universal/Utter/Ultimate/Uhatever Extractor

[JakeSFR]

[Original thread: http://oldforum.puppylinux.com/viewtopic.php?t=87864]

In order to ease unpacking of various archive formats, I forged One Script to Rule Them All (well, at least most of them ).

It's packaged as a ROX right-click app, but the script itself (/usr/local/apps/UExtract/uextract) can be used from command line.
For example - to extract 'archive.tar.gz', 'arch2.7z' and 'somepkg.rpm' from current dir to /root/somedir:

Code: Select all

uextract -o /root/somedir archive.tar.gz arch2.7z somepkg.rpm

Same thing can be done via 'right-click -> Open With -> UExtract'.
BTW, each archive will be always extracted to a separate subdirectory!

If I navigate to https://vivaldi.com/download/ and select 32-bit Linux version it offers me vivaldi-stable_3.7.2218.58-1_i386.deb but Uextract 4.4 is unable to extract the file.

Do you have any idea what might different about this .deb?

Cheers!

There are errors: "ar not installed/executable"
As you can see v3.32 uses dpkg-deb, v4.4 now uses 7z to extract ...

Both are extracting successfull here on my upupbb32 system.

peace

[JakeSFR]

Do you have any idea what might different about this .deb?

Nothing seems different about it, it's a regular DEB, xz compressed, so it's not even zstd.
Any error messages when you try to extract it?

Both are extracting successfull here on my upupbb32 system.

Extracts just fine for me, too.

UExtract uses several tools to unpack DEBs, the first two are ar or 7z. followed by gunzip/bunzip2/unlzma/unxz/unzstd.
If the above fails, the next one is dpkg-deb (full or Busybox's).
And the last one is exploderpm and this one actually fails on that DEB, because it doesn't support xz compressed DEBs.

Greetings!

[greengeek]

Any error messages when you try to extract it?

Thank you both for confirming the deb is ok..
Looks as if it must just a problem when trying to extract that deb using Tahr 6.0.5 and older pups maybe?
(Sorry I should have mentioned I was using Tahr32 6.0 5bit)

@greengeek :-

I've had this happen a number of times, Ian. It's NOT UExtract's "fault", and usually not Puppy's.....though it's possible some of the required binaries ARE getting a bit long in the tooth where Tahrpup's concerned.

Nine times out of 10, it's down to one of two things; either a "bad" download, or, more often, due to packagers not following the proper .deb packaging guidelines, and making a general mess of their packages. And you'd be surprised how often this seems to happen.....

Mike.

[jrb]

"Trying 'ar'..."

/usr/bin/ar is in both devx_tahr_6.0.5.sfs and devx_tahr64_6.0.5.sfs (that's the 64bit version of ar).

So just mount the devx and it should work for you. I usually copy ar and its dependency, libbfd-2.24-system.so from the devx and put it in my pup so I don't have to run with devx mounted all the time.

Cheers, J

[JakeSFR]

I was using Tahr32 6.0 5bit

Ok, so p7zip-9.20 doesn't seem to support the '-tar' switch (it's not 'tar', but type of archive = 'ar'). It works in version 9.38 and newer, though.

And dpkg-deb-1.17.5 doesn't support control.tar.xz yet, it was added in 1.17.6:

* Add support for .deb archives with a control member not compressed
(control.tar) or compressed with xz (control.tar.xz).

The best shot is to go with jrb's suggestion or upgrade p7zip.
___________

EDIT: attaching the ar binary. It's actually Busybox-1.33.1, but with only ar utility enabled.
It's 32bit and statically linked against musl, so should work on any x86 CPU/Linux.
Busybox, because full, static ar is 1130K and this one is only 134K.
You can put it in /usr/local/apps/UExtract/resources after unpacking.

Greetings!

Awesome! Tested both solutions and both worked. Have now grafted that static ar into the resources directory of the original version of uextract that comes in Tahr32 and everything's perfect now.
Many thanks!

@JakeSFR :-

Thanks once again for your continuing support for this essential app. Like jrb, I too use it every day.....sometimes several times a day. And it rarely fails to deliver (on the very odd occasions where it doesn't do what's required, it almost always turns out to be duff downloads or improperly-packed packages).

Both of which are beyond anyone's control. Cheers, mate!

Mike.

[JakeSFR]

I also use it every day.
It's the oldest, still being developed app of mine, I believe; 8+ years.

Take care &

Hi JakeSFR. What's the latest version of PackIt? 1.22? By the way, the link to PackIt in the first post leads to a blank page of the old forum.

[Makoto]

Indexing is a little broken on the old forum here and there at the moment, I think. I tried directly searching for PackIt and UExtract, and the forum's own search engine returned no results.

The post index number matches, though, so let's see...
PackIt-1.22 - a flexible Archiving/Compressing GUI

(tests) ...hmm. That seems to work - for me, at least.

[JakeSFR]

Ah, I fixed the "UExtract original thread" URL, but forgot about PackIt's. The puppy/ string needs to be removed from URL.
It's still ok for the old domain, e.g.: https://murga-linux.com/puppy/viewtopic.php?t=89211

Yes, 1.22 is the latest.

Greetings!

[mikewalsh]

@Makoto :-

Try rockedge's "P-search" (if you haven't already done so).

Best Puppy search engine I've ever used....

Mike.

[Makoto]

Thanks. I was using the board's search engine because I wanted to see how it was affected by the indexing issues, if anything, though.

[don570]

Thanks for keeping this app current.
I opened up fatdog64 8.11 ISO to obtain individual files.

[puppy_apprentice]

I like to check archives before i send them to somebody. There is an option in 7zip:

Code: Select all

7z t "$1"

Maybe you can add option "Check archive" to ROX pop-up menu.

I think that checking archive integrity is somewhat outside of the scope of UExtract.
Besides, some backends don't have this ability at all, e.g. tar or lzop. And how to check integrity of an ISO or a PDF?
Anyway, why not just create a separate right-click utility for that purpose?

You didn't check it. You are bad boy

In Windows 7zip adds this feature to the pop-up menu.

Code: Select all

7zip t

tests ISOs, tars, bz, gz, deb, rpm etc.

It is better to check archive first than wait for errors when you extracting something.

Oh yes, indeed, but it doesn't seem to be reliable enough - with some of ISOs I just created and tested, I got:

Code: Select all

ERRORS:
Unexpected end of archive

even though all files inside are identical with originals.
Besides, 7zip, (Win)RAR, PeaZIP, etc. are archive _managers_, unlike UExtract, so it makes sense for them to do it.

It is better to check archive first than wait for errors when you extracting something.

Checking integrity takes practically the same amount time as extracting (minus the overhead for writing files) for you to find out that the archive is broken, so what's the point..?

And there's still "List contents instead of extracting" option in UExtract, which will tell you (not in all, but in most cases) if there's something wrong with an archive, without actually extracting it.

even though all files inside are identical with originals.

It is always good to check MD5 or SHA of those ISOs.

But nevermind. 7zip is like PackIt and UExtract in one package but with less formats than your tool.

I will made own option for this (but i'm lazy and thought that somebody will made it for me).

Wouldn't it be just a one-liner like this one:

Code: Select all

7za t "$1" && xmessage "OK" || xmessage "NOT OK"

in a script linked to /etc/xdg/rox.sourceforge.net/{OpenWith,SendTo}/.application_x-7z-compressed and possibly others?

However, if some of your archives are encrypted, you'd need, for example:

Code: Select all

urxvt -T "Checking archive integrity" -e sh -c "7za t \"$1\"; sh"

so the user could actually interact with it and provide a password.

Yep, i will add it for all archives that 7zip support. Currently using from console.
And i think that i add it for directories. Because 7zip can test all archives in directory.

Edit: could you check your ISO with isolyzer:

Tried that and everything seems to be in order.
Anyway, I found that 7z fails if ISO contains an empty file. Or a symlink, and it was created with mkisofs' '-rock' option. There may be more causes.
