gmtwhich

Find full path to specified files

Synopsis

gmt which files [ -A ] [ -C ] [ -D ] [ -G[a|c|l|u] ] [ -V[level] ] [ --PAR=value ]

Note: No space is allowed between the option flag and the associated arguments.

Description

which reports the paths to the files given on the command line. We look for the file in (1) the current directory, (2) in $GMT_USERDIR (if defined), (3) in $GMT_DATADIR (if defined), or (4) in $GMT_CACHEDIR (if defined). If found we print the path name to the file, just the directory (see -D), or a confirmation (see -C). The $GMT_USERDIR and $GMT_DATADIR environment variables can be comma-separated list of directories, and we search recursively down any directory that ends with / (i.e., /export/data is a single directory whereas /export/data/ will be searched recursively.) If the file is in the current directory then we just return the relative path (i.e., the file name); otherwise we return the full path.

Required Arguments

files
One or more file names of any data type (grids, tables, etc.).

Optional Arguments

-A
Only consider files that the user has permission to read [Default consider all files found].
-C
Instead of reporting the paths, print the confirmation Y if the file is found and N if it is not.
-D
Instead of reporting the paths, print the directories that contains the files.
-G[a|c|l|u]
If a file argument is a downloadable file (either a complete URL, a @file for downloading from the GMT data server, or @earth_relief_xxy) we will try to download the file if it is not found in your local data or cache dirs. By default [-Gl] we download to the current directory. Append a to place files in the appropriate folder under the user directory (this is where GMT normally places downloaded files), c to place it in the user cache directory, or u for the user data directory instead (i.e., ignoring any subdirectory structure).
-V[level] (more …)
Select verbosity level [w].
-^ or just -
Print a short message about the syntax of the command, then exit (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 exit.
-? or no arguments
Print a complete usage (help) message, including the explanation of all options, then exit.
--PAR=value
Temporarily override a GMT default setting; repeatable. See gmt.conf for parameters.

Examples

To see the path to the file myjunk.txt, use:

gmt which myjunk.txt

To download the 10 arc-minute global relief file from the GMT data server, use:

gmt which -Ga @earth_relief_10m

which will print the path (after downloading if not already present). The file will be placed in the appropriate folder under the user’s GMT_USERDIR. To obtain a GMT example or test file from the GMT data server, try:

gmt which -Gc @hotspots.txt

which will print the path (after downloading if not already present). The file will be placed in the user’s GMT_CACHEDIR directory.
