einfo.pl - query einfo to find all available databases or information about a specific database (field information or links to other NCBI databases)
einfo [-d database] [-f Field Code] [-l Link Name] [-o outfile]
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.
