eaddress - check edirect's notion of your e-mail address (DEPRECATED)
Note: eaddress will not appear in future releases of NCBI Entrez Direct. However, several other commands, such as einfo, take a -debug flag that will reveal an nquire command line containing the email address they pass.
eaddress prints (to standard output) the e-mail address that other edirect(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 EMAIL environment variable is set, edirect will honor it. Otherwise, it will combine a username from the USER environment variable or reported by whoami(1) with a hostname from /etc/mailname or uname(2), attempting to obtain a fully qualified form if necessary.
