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
