BP_EINFO(1p)						User Contributed Perl Documentation					      BP_EINFO(1p)

NAME

       einfo.pl - query einfo to find all available databases or information about a
		   specific database (field information or links to other NCBI
		   databases)

SYNOPSIS

	einfo [-d database] [-f Field Code] [-l Link Name] [-o outfile]

DESCRIPTION

       Command line options:

	 -e/--email
	       Valid email (required by NCBI policy)

	 -d/--db/--database
	       NCBI database to query
	       (default = none, which shows available databases)

	 -f/--field
	       print out information about a specific field code
	       (default = none)

	 -l/--link
	       print out information about a specific link name
	       (default = none)

	 -o/--out
	       outfile
	       (default = STDOUT)

	 -h/--help
	       show this documentation

       As per NCBI's policy regarding eutils access, a valid email is required.  This is not enforced here (if one is provided you will get a
       standard warning), but don't be surprised if this doesn't work after June 1, 2010 unless one is supplied.

       If -d is not specified, field and link arguments are ignored and all available databases are printed instead.

       If either link names or field codes (or both) are specified, nothing else is printed out (only the info requested).  You can specify as
       many fields and/or links as you want by using multiple -f/-l <ARG> on the command line.
