Hello, I have a question regarding some decompression of files on irix I am a problem to unpack, if someone can 'indicate the correct procedure, perhaps I'm missing a file to do the task.
For example, I have a file like this:
Code:
library_IRIX.tar.bz2
software_IRIX.iso.gz

I tried to unzip the files. tar with the command "tar-xvf" and hopefully I can do it but with these files described above. bz2 and. iso.gz I can not do that I used the command "bzip2-d filename. bz2 "nothing but the command is not recognized by irix. :?

IRIX doesn't grok bzip. You'll have expand its horizons with a dose of nekoware: http://nekoware.dustytech.net/index.php?path=current/

Thanks for the help recondas, I have downloaded the files now the load, unfortunately I have some 'fledgling with the management of files on IRIX and UNIX in general I'm trying to learn the basics my horizons are very limited now. ;)

Fortunately the nekoware version of bzip2 doesn't have any dependencies , so it provides a relatively gentle introduction to nekoware.

The file is "neko_bzip2-1.0.5.tardist", download it to an easily accessible folder on the hard drive of your Onyx2. Once you have the file downloaded you can drag-n-drop the file from the File Manager window to the "drop pocket" in Software Manager.

Thanks for help recondas,I could now try to load it to unpack the files. bz2 is only by understanding how to do it with. iso.gz I will try 'to use this file, or try the list of nekoware.

To answer your next question:

No, IRIX doesn't have a loopback filesystem for mounting disk images. You'll need to burn it to a CD or mount the image on a Linux box and move it over to the IRIX box some other way.

Thanks Saq,My problem is that I have the hard drive do I need a CDwriter then, about the files regarding "bz2" I installed the file and unzipping using neko_bzip2 1.0.5 software manager but nothing so I can not figure out how to deal with this type both files. "bz2" and is ". tar.gz" are just inexperienced in these things but if anyone can 'explain step by step how to do well, perhaps I can understand why' do not know the exact command,or I was wrong to use the command "bzip2-d" from winterm? :?

For a bz2 file, you would use the bunzip2 command to uncompress it. For example, "bunzip2 library_IRIX.tar.bz " would create a file called "library_IRIX.tar".

tar is an old format that was originally used for archiving files to tape. On IRIX, use "tar tvf filename.tar" to see the contents of a tar file, and then you can use "tar xvf filename.tar" to extract the contents. For example, "tar xvf library_IRIX.tar". That will probably create a folder/directory called "library_IRIX", inside of which I guess you will find software that you can install.

You might sometimes see .tardist files. They are just regular tar files that happen to contain an installable software image. It is used only on IRIX systems. On some IRIX systems, clicking a link to a tardist file will open it in the Software Manager. On any system, you can use the tar xvf command to extract the installation files, and then you can work with them just like they were regular files.

Sometimes you'll see .tgz files. These are the same thing as .tar.gz files, i.e. tar files that have been compressed with gzip.

gz is a gzip file. On IRIX, you can use the gunzip command to decompress it. For example, "gunzip software_IRIX.iso.gz" will result in a file called software_IRIX.iso - which should be a regular iso file that you can easily use to burn a cd on a Mac or Windows, or Linux PC. If you use Windows, the freeware 7-Zip utility works well with tar, bz2, and gz files. http://www.7-zip.org/

If you have a spare hard drive you can "dd" the image over onto the raw drive, plug it into your system, and work with it that way as well. SGI images will probably be in EFS, other images might be in ISO or Rock Ridge.

Thanks PymbleSoftware, and now I understand that 'a copy command to move from one state to another state from. Iso files without extension, even if not 'very clear syntax.(I did not think there was written somewhere that he was on techpubs "dd" but now I know that after you tell me!)
For example, I printed the manual commands from IRIX techpubs I found a way to use this command:
Code:
gzip"filename"
gunzip"filename"
gzcat"filename"

in order if you use "gzip" compress a file and create a file with the extension. "gz"
Then if I use "gunzip" to decompress the same file and I remove the extension. "gz"
but if I use "gzcat" I see its contents.
My problem still remains the extension:
Code:
. bz2 or
. tar.bz2

I have successfully installed the file "neko_bz2 1.0.5.tardist" but there was and how when I enter the command:
Code:
bunzip or
bzip

The system does not recognize it if someone can 'explain to me just this thing because I do not know what to do and the manual does not report it as a command in IRIX I would be very grateful, just to understand where mistake, I just want to be able to unpack the file ". bz2" or with ". tar.bz2".

That's because you haven't told IRIX where to look for the bzip/bunzip executables. The short-term work-around is to implicitly state the entire path to the command in question, something like
Code:
 /usr/nekoware/bin/bunzip2 yourfile.tar.bz2
The long-term fix is to download neko_fixpath.tar.gz, and run the encapulated script to add nekoware to the search path of your system.

What might be more helpful to you in the long run is some sort of unix reference text in your native language. Even if it isn't IRIX specific, it'd almost certainly be better than dealing with an unfamiliar operating system while simultaneously trying to translate us on the fly.
