NAME

       einfo - look up general NCBI Entrez database information

SYNOPSIS

       einfo [-help] [-dbs] [-db name] [-fields] [-links]

DESCRIPTION

       einfo  looks  up  general information about either an individual NCBI Entrez database with
       which other Entrez Direct commands can work or the set of available databases as a whole.

       einfo is also the name of an tool for accessing contents of local EPUB files.  To  resolve
       this  ambiguity,  Debian  systems  with  both  EPUB  utilities and Entrez Direct installed
       arrange for the EPUB-related executable to have the name einfo.epub(1) and for einfo to be
       a wrapper script that examines its usage and proceeds to run whichever of einfo.epub(1) or
       einfo.ncbi looks like a better fit.
