Hi,

Is there a more efficient way to perform ztail. I could use 'zcat f.gz
| tail'. But this means that it needs to go through the file until the
end. It would be more efficient to just check the end (as `tail f.txt`
does it). Is there a way to make ztail more efficient?

Peng

Not in general, no. The compressed file can't be decompressed from 
random locations.

There might be some options for doing what you're suggesting if 
--rsyncable is used during compression (which it usually isn't) and if 
someone would like to code up something for gzip (which would be 
nontrivial).
