mgd77path - Return paths to MGD77 cruises and directories
mgd77path NGDC-ids [ -A[-] ] [ -D ] [ -Iignore ] [ -V[level] ]
Note: No space is allowed between the option flag and the associated arguments.
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.
Can be one or more of five kinds of specifiers:
(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].
