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
