Homework and Emergencies Emergency UNIX and Linux Support Perl script logging via Shell script Post 302473457 by DGPickett on Saturday 20th of November 2010 11:01:43 AM

Maybe this is partly about logging on a buffered fd/FILE* like stdout, not unbuffered stderr, and no periodic flush(), with lost output when the script hangs and has to be killed? Logging through a pipe chain has a similar latency problem with potential lost output. One workaround for infrequent logging is to log by
Code:
system("echo 'Message' >>log_file")

or

system("date '+%Y-%m-%d %H:%M:%S Message' >>log_file")

or equivalent calls in perl using ``.
