samtools-head - view SAM/BAM/CRAM file headers

       Written by John Marshall from the University of Glasgow.

       By default, prints all headers from the specified input file to standard output in SAM format.  The input
       alignment  file may be in SAM, BAM, or CRAM format; if no FILE is specified, standard input will be read.
       With appropriate options, only some of the headers and/or additionally some of the alignment records will
       be printed.

       The samtoolshead command outputs SAM headers exactly as they appear in the input file; in particular, it
       never adds an @PG header itself.  (Other samtools commands add such @PG headers to facilitate  provenance
       tracking  in analysis pipelines, but because samtoolshead never outputs more than a handful of alignment
       records it is unsuitable for use in such contexts anyway.)
