[Vladimir Sakharuk]

Looks like I am hitting zip/gzip incompatibilities.  :( thank you all.

How could I make zgrep work?

zgrep shows error on archive while 
unzip -t
unzip
unzip -p|grep
work without problem

~>unzip -t aa.zip
Archive:  aa.zip
    testing: aa        OK
No errors detected in compressed data of aa.zip.

4376671663 Jan 26 22:42 aa
386634752 Jan 28 16:21 aa.zip

Zgrep works on other archives without problem.

Thanks.
