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

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
