Listing contents of .tar.gz files
Hi All,

I would like to know couple of ways to list the content available in tar and gzipped file without extracting.

i.e., I would like to display the contents of test.tar.gz without extracting.

Note :: please suggest a command other that tar -ztvf

You literally cannot. There is no way. This is because of the way tar works, a stream rather than block-based.

Thanks Corona! I missed and zapped the "without extracting"....

What's wrong with:-
Code:
gunzip -c file.tar.gz | tar -tvf -

It works for me on RHEL 6.3

The extraction is all in-stream / piped so never writes to disk, but for a large file it might take a while.

I read it that he didn't want to extract it to disk and then scan it, hence my suggestion. I feel such a fool. Smilie

The only other way I could suggest would be to read the output from when the file was created, assuming that this was saved away. We have some whopping tar files created daily (and purged after a week) and the process to create them is something like:-
Code:
(tar -cvf - .|gzip > $target_tar_gz ) 2>$target_tar_gz.list
