Archive List

(1/4) > >>

CentralWare:
Good morning everyone!
I need a little brain-storming to create a function whose job is to determine how to extract an archive file based on the filename.
However, of course, there's a million archive formats out there, so we need to build a laundry list of file extensions along with the command to extract with.

For example:

--- Code: ---case $1 in
   *.tar)       CMD="tar -xf" ;;
   *.tar.gz)    CMD="tar -zxf" ;;
   *.tar.bz)    CMD="tar -jxf" ;;
   *.tar.bz2)   CMD="tar -jxf" ;;
   *.7z)        CMD="7z x -so" ;;
   *.rar)       CMD="unrar x -r" ;;
   *.zip)       CMD="unzip -a" ;;
esac

--- End code ---

The goal here is to have a working list of commands of supported software, create extensions if necessary for software we don't already have in the repository and have this function detect whether or not said extensions are currently installed.  Please list all of the file extensions you can think of along with their associated command to EXTRACT into the CURRENT directory.  The above examples were "off the top of my head" so they may not be completely accurate.

The "ultimate" goal is to have the fewest number of extensions needing to be installed in order to support the largest number of archive formats.

This function will also be supporting ISO, RPM, DEB, CPIO and other containers, we probably won't need to support extensions like CAB for obvious reasons, but there's archives out there such as ACE, ALZ, LZH, etc. which aren't overly common today, but worthwhile to implement if they don't require closed source software.

Any file extensions you can think of that you know how to extract...  please feel free to contribute!
LOL - if five people have already listed *.xz)   CMD="tar -xf" ;; please refrain from adding a sixth! :)

My first comment on this, that you can use the pipe char to reducing repetition in your case statement which works as an "OR" like this:


--- Code: ---   *.tar.bz|*.tar.bz2)      CMD="tar -jxf" ;;
--- End code ---

I use wimextract to extract some fonts from the iso.
Using a computer that have a M$ license ;)

I installed wimlib in my Arch linux system to get the wimextract program.

So the format wim and cab can be usefull, even if "we" don't want to support the M$ Corp.


--- Code: ---wimextract install.wim 1 /Windows/{Fonts/"*".{ttf,ttc},System32/Licenses/neutral/"*"/"*"/license.rtf} --dest-dir /home/patrik/fonts

--- End code ---

Yes, but for sake of being able to quickly "see" what packages we have on the list vs. what needs to be completed, I currently have two lists going; one for *.tar.gz and other fully listed archives, and a separate list for hybrid/combined extensions such as .tgz - they're the same commands, I'm just trying to cover all bases at the start and we'll combine them once we're ready to push the changes upstream.  Or not...  We'll see where things land in the end! :)

When combining similar archives, LZH and LHA would go together, but the initial list will be sorted alphabetically to ensure we get all of the necessary packages in here so "OR"ing the list is a little premature just yet.

As for M$, I'm doubtful they'll be putting out too many 'nix based source code packages (which is what this archive project is focused on - extracting people's source code and support packages) so if I (ahem) accidentally leave out a couple which weren't intended for our side of the fence, I'm pretty certain they won't be missed. :)

IMHO, I think 7-zip (ver 24.09) linux version, covers "everything". https://www.7-zip.org/download.html
Please read its help for confirmation that any format can be manipulated from command line.
