Is it safe to pipe the output of several parallel processes to one file using >>?

Question

I\'m scraping data from the web, and I have several processes of my scraper running in parallel.

I want the output of each of these processes to end up in the same f

Answer 1

As mentioned above it's quite a hack, but works pretty well =)

( ping stackoverflow.com & ping stackexchange.com & ping fogcreek.com ) | cat

same thing with '>>' :

( ping stackoverflow.com & ping stackexchange.com & ping fogcreek.com ) >> log

and with exec on the last one you save one process:

( ping stackoverflow.com & ping stackexchange.com & exec ping fogcreek.com ) | cat
