NAME

       mgd77path - Return paths to MGD77 cruises and directories

SYNOPSIS

       mgd77path NGDC-ids [  -A[-] ] [  -D ] [  -Iignore ] [  -V[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). If no file extension is given then
              we search for files with one of the four known extensions.  The search  order  (and
              the  extensions)  tried  is MGD77+ (".nc"), MGD77T (".m77t"), MGD77 (".mgd77" ) and
              plain text file (".dat").  Use -I to ignore one  or  more  of  these  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|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].

       -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
              just use -).

       -+ 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  all  options,
              then exits.

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
