On something of minor tangent, if you're writing scripts in either 'sh'
or 'bash', you may find the following web site helpful:

  http://www.shellcheck.net

shellcheck is also available as a port, if you don't want to be pasting
your shell code into somebody else's web site.  The last time I checked,
the port brings in several other ports, so I tend to use the web site.
