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

Generally, no.

On Linux this might be possible, as long as two conditions are met: each line is written in a one operation, and the line is no longer than PIPE_SIZE (usually the same as PAGE_SIZE, usually 4096). But... I wouldn't count on that; this behaviour might change.

It is better to use some kind of real logging mechanism, like syslog.
