Unzipping .tar.gz files on IFS

[stewartp]

Hi,
We get a .tar.gz file ftp'd to our IFS each week and I would like to know if I can unzip the file using standard system I functionality via a program so the whole process can be automated.
Currently, I'm unzipping it manually, then copying the contents back to the same IFS directory and then calling required functions.

Regards

Hi Stewart,

You may want to try the STRPCCCMD command to invoke whatever your flavour of unzipping program is from the 400. Would be a quick and dirty way of doing it if what Jamie suggested doesn't work out for you.

Re: Unzipping .tar.gz files on IFS

But how do you structure the command to perform the unzipping the tar.gz file. For example the tarfile on IFS is;
/directory1/directory2/abc.tar.gz

how do enter the command line to unzip files to the same directory. Findind it difficult to find that information.

Thanks

adding zip/unzip to system i - all need files in zip file attached

http://www.redbooks.ibm.com/abstracts/tips0283.html

Here are the steps to add the Unzip and Zip functions to your System i server:

1. Go to the following File Transfer Protocol (FTP) site and download the archives:
   
   

   http://www.ctan.org/tex-archive/tools/zip/info-zip/UNIX/AIX/

   
   In our case, we download these files:
   
   zip23x-aix43.zip To compress (zip) files
   unz550x-aix5L.tar.gz To uncompress (unzip) files
   
2. Place these files somewhere on your System i server. In this example, we use /home/zip.
   
3. You will also need the gunzip tool to uncompress the unz550x-aix5L.tar.gz file. Download the tool from the following Web site:
   

   http://www-03.ibm.com/servers/enable/site/porting/iseries/overview/gnu_utilities.html

   
   
   Place the file in the same directory as the other two files.
   Review the license agreement for the downloaded tools.
   
4. Sign on to your System i server and start an i5/OS PASE terminal with the command:
   
   

   CALL QP2TERM

5. Change to the /home/zip directory:
   
   

   cd /home/zip

6. The unzip file is a compressed file. Uncompress this file:
   
   

   uncompress gzip.1.2.4a.tar.Z

7. Untar? the gzip tar file:
   
   

   tar -xvf gzip.1.2.4a.tar

   It installs the executable files under the /usr/local/bin directory.
   
   
8. Update the PATH variable with the /usr/loca/bin directory by running this command:
   
   

   export PATH=$PATH:/usr/local/bin

9. Uncompress the unz550x-aix5L.tar.gz file using this command:
   
   

   gunzip unz550x-aix5L.tar.gz

10. ?Untar? the uncompressed file:
    
    

    tar -xvf unz550x-aix5L.tar

    It creates the directory unzip-5.50.
    
11. Change to this directory:
    
    

    cd unzip-5.50

12. Enter the following command:
    
    

     unzip

    It shows you the command usage text.
    
    
13. To run the command from any directory and any terminal window, you have to copy the unzip file into the /QOpenSys/usr/bin directory:
    
    

    cp unzip /QOpenSys/usr/bin

14. Switch back to the directory to which you have downloaded the files:
    
    

    cd /home/zip

15. Now check whether unzip is really working. The Zip program on our system is packed in the zip file - zip23x-aix43.zip, so we can try on that one. Verify that you are in the directory in which the zip23x-aix43.zip file is located. Enter the following command:
    
    

    unzip -d ./zip zip23x-aix43.zip

16. This creates a directory named zip and places all files into that directory. Change to this directory:
    
    

    cd zip

17. Issue the following command to see if the program is working:
    

     zip

    This will show the usage notes.
    
18. To make the command available in every i5/OS PASE terminal session, copy the program into the /QOpenSys/usr/bin directory.
    
    

      cp zip /QOpenSys/usr/bin

19. To use both commands (zip and unzip) in QShell, make another copy of the programs into the /usr/bin directory by running 2 commands:
    
    

    cp /QOpenSys/usr/bin/zip /usr/bin 
    cp /QOpenSys/usr/bin/unzip /usr/bin

    Now zip and unzip are available for the next QShell terminal.

Re: Unzipping .tar.gz files on IFS

Hi all,

I have installed the zip/unzip utilities posted by Jamie. It is working only that i have found out that i cannot work on files larger than 2Gig.

I am zipping large savefiles more than 2G in size. Is there some fix available?

Thanks,
Greg

Re: Unzipping .tar.gz files on IFS

Greg is this a limitation of the size of the folder on the IFS?

Re: Unzipping .tar.gz files on IFS

Hi Jamie,

Sorry for the late response on this. It is not a limitation of the folder in the ifs. I think it is a limitation on the Zip program because I can able to zip files but for those files which are larger than 2Gig, all i get is a log which says something like :
zip warning: name not matched: mybigfile.savf
zip error: Nothing to do! (/bckup_dir/CLNUP05_06/mybigfile.zip)

Re: Unzipping .tar.gz files on IFS

Okay dont laugh this is actually this easy...

I have 4 .csv files created in QTEMP
I need to email these to the user that
just created them....

created folder on root called ZIP
(this works fine for me cause Im the only one doing this)
You will need to create subfolders by job to release this
to the hounds.

MD DIR(zip) DTAAUT(*RWX) OBJAUT(*ALL) 

In my case I just ran 4 cpytoimpf commands

CPYTOIMPF FROMFILE(QTEMP/WKR20WORK1) TOSTMF('zip/wkr20work1.csv')
STMFCODPAG(*PCASCII) RCDDLM(*CRLF)      

CPYTOIMPF FROMFILE(QTEMP/WKR20WORK2) TOSTMF('zip/wkr20work2.csv')
STMFCODPAG(*PCASCII) RCDDLM(*CRLF)      

CPYTOIMPF FROMFILE(QTEMP/WKR20WORK3) TOSTMF('zip/wkr20work3.csv')
STMFCODPAG(*PCASCII) RCDDLM(*CRLF)      

CPYTOIMPF FROMFILE(QTEMP/WKR20WORK4) TOSTMF('zip/wkr20work4.csv')
STMFCODPAG(*PCASCII) RCDDLM(*CRLF) 

Then to get them to the zip file......named profit.zip

STRQSH CMD('jar cfM zip/profit.zip zip/*.*') 

*** Note dont run this I think it would zip the entire IFS into a zip file
that can never turn out GOOD!

STRQSH CMD('jar cfM zip/profit.zip *.*') 

anyway then you have your files all zipped up and
can send them to anyone you wish with your favorite
email process. (there are a couple posted on the site)

Re: Unzipping .tar.gz files on IFS

Okay now I have this zip file that I can create at will...

What is the easiest way I can email this file from the IFS?

Re: Unzipping .tar.gz files on IFS

This'll do it ... it's really great software... it's for free - no configuration on the i required.
Only does (up to) 4 attachments though.

Re: Unzipping .tar.gz files on IFS

Thanks Kit...combined with my zipping code I only need one attachment
