MGD77PATH(1)                 Generic Mapping Tools                MGD77PATH(1)


NAME

       mgd77path - Get full pathname for MGD77 files


SYNOPSIS

       mgd77path NGDC-ids [ -D ] [ -Iignore ] [ -P[-] ] [ -V ]


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.

       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].


OPTIONS

       No space between the option flag and the associated arguments.

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

       -I     Ignore certain data file formats from consideration. Append
              a|c|m|t to ignore MGD77 ASCII, MGD77+ netCDF, MGD77T ASCII or
              plain tab-separated ASCII table files, respectively. The option
              may be repeated to ignore more than one format.  [Default
              ignores none].

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

       -V     Selects verbose mode, which will send progress reports to stderr
              [Default runs "silently"].  Reports the total number of cruises
              found.


EXAMPLES

       To obtain pathnames for cruises 01010008 and 01010007, run

       mgd77path 01010008 01010007

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

       mgd77path 01010008 01010007 -Ia -It

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

       mgd77path -D
