       elink - look up related NCBI Entrez records


       elink   (edirect -link)   [-help]   [-related]  [-target dbname]  [-name name]  [-db name]
       [-id ID(s)]  [-input filename]  [-cmd command]   [-holding provider]   [-cited]   [-cites]


       elink  follows  links  between  Entrez  databases, either extending an existing edirect(1)
       pipeline or honoring explicit -db and -id (or -input) options.

       It has two implementations: a shell implementation on top of nquire(1)  and  a  historical
       Perl  implementation  that  amounts  to  running  edirect  -link,  enabled  by setting the
       environment variable USE_NEW_EDIRECT to a false value  as  described  in  the  ENVIRONMENT
       section.  Some options are implementation-specific, as detailed below.


   Destination Database
              Look up neighbors in the same database.

       -target dbname
              Follow links to another database.

       -name name
              Follow  an explicit link name such as pubmed_protein_refseq, pubmed_pubmed_citedin,
              or pubmed_pubmed_refs.

   Direct Record Selection
       -db name
              Entrez database name for immediate lookups.

       -id ID(s)
              Unique identifier(s) for immediate lookups.

       -input filename (shell implementation only)
              Read identifer(s) from file instead of standard input.

   Advanced Control
       -cmd command
              Command type (returns eLinkResult XML):
              history (shell implementation only)
                     Save results in Entrez history server
                     Neighbors or links
                     Neighbors with computed similarity scores
              acheck All links available
              ncheck Existence of neighbors
              lcheck Existence of external links (LinkOuts)
              llinks Non-library LinkOut providers
              llinkslib (Perl) or llibs (shell)
                     All LinkOut providers
                     Primary LinkOut provider.

       -holding provider (Perl implementation only)
              Name of LinkOut provider.

   PubMed Citation Lookup
       -cited References to this paper.

       -cites Publication reference list.

   Batch Processing
       -batch (Perl implementation only)
              Bypass Entrez history mechanism.

   Miscellaneous Arguments
       -help  Print usage information.


              Whether to use the current shell implementation or revert to  the  historical  Perl
              implementation.    Canonical   true  values  are  1,  on  (case-insensitive),  true
              (case-insensitive), and yes (case-insensitive); canonical false values are  0,  off
              (case-insensitive), false (case-insensitive), and no (case-insensitive).
