"Unexpected EOF" means the file ended before it should have, like whatever uploaded the file aborted halfway through.

"999999_ipd0018.001.gz" is probably corrupt or just plain empty. You'll notice jar printed every filename leading up to this one, but not this one. That's because jar didn't succeed in extracting this file. I suppose it began extracting it, hit end-of-file (EOF) and quit.

Thanks 999999_ipd0018.001.gz is having data. I found another interesting thing

Step 1 : I did

gunzip 99999_ipd0018.001.gz

in one window

Step 2: Then I did

tail -f 99999_ipd0018.001.gz

on other window

step 1 terminated with the error . but step 2 is keeping on running it is running for almost 5 hours and all I see is all data is repeating. I think the file is corrupted. Is there any way to see the data in the file ?

Thanks
Arun

If there is, you'll have discovered a revolutionary new form of data compression where you can throw away half a zip file and still get its contents back.

I'm not sure what you're doing by trying to read from a binary .gz file with tail, neither gunzip nor tail work that way.
