PROGRAM:
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
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
