Combining tar and gzip errors on AIX system.

The below tar of folder 1043 command works fine on AiX system.

Code:
tar -X ./exclude.txt -cvf /backup/App_Bckup.tar ./1043 | tee /tmp/tar.out
gzip /backup/App_Bckup.tar ./1043

I wanted to combine the tar and gzip as a single command .. reason bieng the tar ball creation forst and then the gz file creation would force the disk space to run out.

Below is the combine command.

Code:
tar -X ./exclude.txt -cvf /backup/App_Bckup.tar ./10203| gzip >/backup/App_Bckup.tar.gz

However, i get the below error:

Code:
tar: ./1043/B2KCOMP/b2kcomp/15002S10485964.70600 could not be archived
tar: ./1043/B2KCOMP/b2kcomp/15002S10879272.70598 could not be archived
tar: ./1043/B2KCOMP/b2kcomp/15002S11076030.70600 could not be archived
tar: ./1043/B2KCOMP/b2kcomp/15002S11600848.70600 could not be archived
and so on ....

When i check all the files that error they have 's' in the file permission as seen below:

Code:
ls -ltr ./1043/B2KCOMP/b2kcomp/15002S10485964.70600
srwxrwxrwx    1 user1   dba               0 Feb 15 18:13 ./1043/B2KCOMP/b2kcomp/15002S10485964.70 600

If i grep for "15002S10485964" in the successful tar command's output i dont find any entry.

Code:
grep 15002S10485964 /tmp/tar.out

No results found.

Even

Code:
tar -tvf /backup/App_Bckup.tar | grep 15002S10485964
No results found.

Can you please suggest if and how can I combine the tar and gzip and avoid the error

I'm baffled to learn the AIX tar version doesn't provide the z option.


Writing the tar red output to a file (-f /backup/App_Bckup.tar) will prevent it to write to stdout, i.e. the pipe to gzip. The latter will only receive the "Verbosely list files processed." (c.f. man tar), a list of file names.




As frequently proposed, a search of this site might have helped: How to tar a directory in AIX?


Try
Code:
tar -X ./exclude.txt -cf - ./10203 | gzip -c >/backup/App_Bckup.tar.gz

@Rudic with your suggestion tar -X ./exclude.txt -cf - ./1043 | gzip -c >/backup/App_Bckup.tar.gz I still get the below error messages:

Code:
tar: ./1043/B2KCOMP/b2kcomp/15002S10485964.70600 could not be archived
tar: ./1043/B2KCOMP/b2kcomp/15002S10879272.70598 could not be archived
tar: ./1043/B2KCOMP/b2kcomp/15002S11076030.70600 could not be archived
tar: ./1043/B2KCOMP/b2kcomp/15002S11600848.70600 could not be archived
and so on ....

I'm helpless with that little context you give. What's so special with those files? Does tar work without the gzip? Does it work with other files, e.g simple text files? In another directory? Without the exclude file? On one single file?


Do a step by step analysis!

To me it seems quite normal... I have never heard of tar being able to archive sockets... Look at the name of the files do they seem ordinary to you?
