Using fping and redirecting stout and stderr to the same file.

fping -lDf IPlist >IPoutput 2>&1

The "host unreachable" error messages in the file have no timestamps.

How do I get timestamps on those?

0

fping -lDf IPlist 2>&1 | logger

Then check the syslog, typically your output will appear in /var/log/messages or /var/log/syslog

A side effect of syslog is that it timestamps all entries.
