eaddress - check edirect's notion of your e-mail address
prints (to standard output) the e-mail address that other
(1) subcommands will send by default to have someone to notify
in case a runaway script causes problems with an NCBI Entrez server. If the
environment variable is set, edirect
will honor it.
Otherwise, it will combine a username from the USER
variable or reported by whoami
(1) with a hostname from
(2), attempting to obtain a fully
qualified form if necessary.
