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

).

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:

Hi SFR,

I'm running Precise 5.6 and having installed 7z (full) then using right-click on a few different file types - all went well until I right-clicked on the Windows/Wine .exe file below.

I'm not sure if -after deleting the final three (.gz) characters- it is possible to unpack it (especially if it is effectively already a single file as opposed to a directory of files).

My regards and thanks

Hey Jasper, thank you for the report.

No, this one seems not to be a self-extracting archive, so UExtract/7z won't handle it.
Strangely, even ResourceHacker (under Wine) can't open this file, maybe it's too old:

in akita, 7z is a symlink to 7zr, which is a static bin around 200kb - can't remember where i got it though... not sure if it meets the requirements..

EDIT: terminal says 7-Zip (A) 4.58 beta

anyway, the command line works fine, with -o . file1 file2 file3

i tested gzipped pets, .tar.xz, sfs3 (gzipped), and tar.bz2 .. all worked Smile

but before anything would work through ROX, the AppRun needed to be changed to rxvt from urxvt ... maybe a check in AppRun to see which terminal to use?

I tested with mrxvt, rxvt, .. worked fine.. termit didn't ..
termit just shows the uextract error you get when it receives no options..

I love this, BTW.. so many formats supported..

EDIT2: Where does the support for xz compressed pets and sfs files reside? Within your script or within the pet2tgz/dir2sfs script in various puppies themselves? I don't have any to test in akita, but presume they would not be supported, as I didn't 'backport' those updates from woof, IIRC..

Have posted already in abushcrafter's Improving The Wrappers From Xarchive http://www.murga-linux.com/puppy/viewtopic.php?t=56651 so I know what's that all about .

SFR :
The code looks really fine !

Have not tested it, but (probably)will if xarchive or pupzip fails .

( Had no clue to get 7z to compile that time, but will look into my archives - still running Puppy-4.3)

Update: version 0.92

Reading through the thread that Karl posted link to, I noticed a script posted by Amigo, so I added some formats from there to UExtract:
.cbt
.cpio.lzma
.cpio.7z
.cpio.z
.cpio.gz
.cpio.bz
.cpio.bz2
.tar.z

Other new formats (all handled by 7z):
.chm
.cramfs
.dmg
.fat (not tested, could not find/create one)
.msi
.vhd
.wim

And:
.pup (just the 1st stage, i.e. unzipping to these 3 'dotpup.tar.gz' 'dotpup.sh' and 'md5sum.txt' files)

Note: some of these (and previous) formats are not directly accessible through the main level of right-click menu.
In such cases, use "Open With/Send To" submenu.

What else:
- support for .7z multi-part archives (archive.7z.001 ...)
- if given extension is not supported, don't exit, but instead try to use 7z on it.
- in a bit hacky way, but I also added '-l' parameter that lists all supported extensions

Version 0.92 uploaded, see the first post!

Ok, no further problems reported, so let's make it 1.0:
- added: '-d' option - dependency check
- changed: output directory will be named 'fullarchname_extracted', e.g.: 'archive.tar.gz' will become 'archive.tar.gz_extracted'

First post updated!

Hi again SFR,

Your v 1.0 seems to be working well with Precise 5.6, but as I didn't see the new -d option and as I don't really understand its use (my deficiency) would you kindly explain it in a bit more detail?

My regards and thanks

Addendum:

Thank you for your explanation below. Now I understand how to use it - your -d option is a final touch which is both useful and welcome; especially for non-slacko users.

Hi Jasper

This option is available only through command line, see screenshot.
BTW, just type uextract to display short help msg. Wink

Update, version 1.1

- New formats/extensions:

.b64
.bfe (not an archive - it's encrypted file created with bcrypt)
.cb7
.cpio.lzo
.cpio.xz
.j
.ja
.little (??? - found in .mozilla dir, but it's .zip really)
.lzh
.maff
.mht (handled by my own, crude routine - extracts only base64 encoded stuff from .mht web archives)
.sb (Slax module)
.xpi
.xzm (Porteus module)
.zi (renamed .zip)
.zpi (renamed .zip)

- .sfs (as well as .xzm and .sb) images are now being extracted directly, using unsquashfs4, which is lot faster than mounting'n'copying
- Minor internal improvements

Update, version 1.2

New formats/extensions:
.apk
.bau
.cpl
.crx
.dll
.ear
.nsis
.otp
.otg
.ots
.ott
.pdf (uses 'pdftotext' and 'pdfimages' to extract text & pictures; rather experimental)
.pk3
.pk4
.slp
.sob
.swm
.stw
.tar.lz
.tlz
.war
.zipx

Also, ffmpeg/avconv dependent formats:
.3gp
.avi
.flv
.mkv
.mov
.mp4
.mpeg
.mpg
.ogg
.ogv
.vob
.wmv
Tries to extract audio & video streams.
Video stream ends up inside the same type of container as the source, audio stream is being extracted in a bit more intelligent way.
Although tested and seems to work quite nice in latest Slacko & Precise (with most of videos I tried), the above is highly experimental.

- added exploderpm & rpm2cpio as possible tools for extracting .rpm (in case if 7z is not present)
I completely forgot about 'exploderpm' tool - it's OOTB in Slacko (and probably others).
@Sc0ttman: so, extracting .rpm will work now in Akita!

- added warning message and prompt if '.run' or '.shar' archive is about to be launched (timeout=10sec & defaults to "no").

PS. Don570 gave me an interesting idea to selectively add entries to right-click menu, depending on which of needed tools are installed in target Puppy.
However, I'll leave it for now, since there's too many exceptions and some of formats/extensions can be handled by more than one tool (like .rpm above), so I have no clear vision how to nicely implement this.
But the idea itself is neat...maybe later/elsewhere.

Note for FatDog users:

UExtract seems to work pretty well on this Pup, just before installing, make sure to create one symlink:

good work.

couple of notes...
I find with 7z sfs 3 and 4 are handled but symlinks do not extract correctly..you get a text file containing the path...not sure if that still applies but it is very handy to grab a file even on windows. I considered a workaround but as you mention unsquahfs is probably a better solution.

I built a custom 7za as a static as I found 7z could not find its own shared library under xarchive.... wondered if you had any problems. The sources are quite modular/customizable so in my case I only included formats not covered by standard linux utilities. I also included rar into the static.

One bonus bunny was having a standard format for use in xarchive so one wrapper could handle many formats. we all love 7zip Smile

thats it
have fun

UExtract is fantastic...

Just a quick question, if I keep the static 7z bin i got in akita, will uextract still use exploderpm/rpm2cpio or would i need to remove 7z for that to workl??

Also, techno made a start at at GUI for tar or something... How is uextract at listing archive contents before unpacking/mounting them?? .. If it can list contents of most filetypes too, then it might be a good project for a gtkdialog frontend..
