Oh – you might want to include the –keep-order option as well so your results 
come back in file input order.

Hi – redirect output as normal:

parallel ‘zgrep foo {} | grep bar | grep 192.168.1.100’ ::: 201612*.gz > 
grep_hits.txt

Not as written if you want the 2nd and 3rd grep to have been parallelized.

As written, only the 1st zgrep will be.

Try this instead:

parallel ‘zgrep foo {} | grep bar | grep 192.168.1.100’ ::: 201612*.gz


right make sense, How do I redirect the output to a file?

Hi I have multiple compressed files that I need to run grep against.

I am trying to find 'foo', 'bar' and '192.168.1.100' against all the compressed 
log files.

This will work?

ls 201612*.gz | parallel zgrep foo {} | grep bar | grep 192.168.1.100

Thanks for such an awsome tool!
