I was looking for a tool to display the continuous ping loss to multiple hosts, and I looked at mtr as it already has the display I was thinking about. I saw that it has this option which sounded promising:

  -F FILENAME, --filename FILENAME
          Reads the list of hostnames from the specified file.

Unfortunately, I cannot understand what mtr does with this list of hostnames. It seems to only pick up the first one from the list and report on it.

How is the "list of hostnames" used by mtr?

4 years too late, but I figured it out.

https://github.com/traviscross/mtr/pull/169/commits/c419873aceb7c416cea91724f3e282befc56ecae

From the commit log:

[...] Also, multiple host names will now work in all non-interactive modes (i.e. report, txt, json, xml, raw, csv) instead of just CSV mode.

In interactive mode it latches onto the 1st host. I was hoping I could just get a sidescrolling multi-host ping ... no dice
