NOTE: This app has been written on Slacko-5.6/5.7 and works best in this pup, but should work well also in other (rather newer) Puppies.

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/bin/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

[SFR]

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:

[sc0ttman]

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

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)

Hey Sc0ttman

[SFR]

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!

Greetings!

[SFR]

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!

Greetings!

[Jasper]

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.

[SFR]

Hi Jasper

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

Greetings!

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

First post updated!

Greetings!

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:

[mikeb]

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

thats it
have fun

Mike

[sc0ttman]

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..
