NAME
       mgd77path - Return paths to MGD77 cruises and directories


SYNOPSIS
       mgd77path NGDC-ids [ [-] ] [  ] [ ignore ] [ [level] ]

       Note: No space is allowed between the option flag and the associated arguments.


DESCRIPTION
       mgd77path  returns the full pathname to one or more MGD77 files. The pathname returned for a given cruise
       may change with time due to reshuffling of disks/subdirectories.


REQUIRED ARGUMENTS
       NGDC-ids
              Can be one or more of five kinds of specifiers:

              1. 8-character NGDC IDs, e.g., 01010083, JA010010etc., etc.

              2. 2-character <agency> codes which will return all cruises from each agency.

              3. 4-character <agency><vessel> codes, which will return all cruises from those vessels.

              4. =<list>, where <list> is a table with NGDC IDs, one per line.

              5. If nothing is specified we return all cruises in the data base.

              (See  mgd77info  -L  for  agency  and  vessel  codes).  The  ".mgd77"  or  ".nc"  extensions  will
              automatically  be  appended, if needed (use -I to ignore certain file types). Cruise files will be
              looked  for  first  in  the  current  directory  and  second  in   all   directories   listed   in
              $MGD77_HOME/mgd77_paths.txt [If $MGD77_HOME is not set it will default to $GMT_SHAREDIR/mgd77].


OPTIONAL ARGUMENTS
       -A[-]  Display  the  full  path  to  each cruise [Default]. Optionally, append - which will list just the
              cruise IDs instead.

       -D     Instead of cruise listings, just show the directory paths currently used in the search.

       -Iignore
              Ignore certain data file formats from consideration. Append a|c|t to ignore  MGD77  ASCII,  MGD77+
              netCDF,  or  plain  tab-separated  ASCII  table files, respectively. The option may be repeated to
              ignore more than one format. [Default ignores none].

       -V[level] (more ...)
              Select verbosity level [c]. Reports the total number of cruises found.

       -^ or just -
              Print a short message about the syntax of the command, then exits (NOTE: on Windows use just -).

       -+ or just +
              Print an extensive usage (help) message, including the explanation of any  module-specific  option
              (but not the GMT common options), then exits.

       -? or no arguments
              Print a complete usage (help) message, including the explanation of options, then exits.

       --version
              Print GMT version and exit.

       --show-datadir
              Print full path to GMT share directory and exit.


EXAMPLES
       To obtain pathnames for cruises 01010008 and 01010007, run

              gmt mgd77path 01010008 01010007

       To  obtain  pathnames  for cruises 01010008 and 01010007, but only if there are MGD77+ version in netCDF,
       run

              gmt mgd77path 01010008 01010007 -Ia -It

       To see the list of active directories where MGD77 files might be stored, run

              gmt mgd77path -D
