clear¶
Delete current default settings, or the cache, data or sessions directories
Synopsis¶
gmt clear all | cache | data[=planet] | sessions | settings [ -V[level] ]
Note: No space is allowed between the option flag and the associated arguments.
Description¶
The clear command allows users to delete their entire user cache, data, or sessions directories, and in modern mode their defaults settings (i.e., gmt.conf), or all of the above.
Optional Arguments¶
- all
Deletes all the items under the control of the individual targets.
- cache
Delete the user’s cache directory and all of its contents.
- data[=planet]
Delete the user’s data download server directory and all of its contents. Alternatively, append =planet for a specific planet and we only delete data for that sub-directory [all planets].
- sessions
Delete the user’s sessions directory.
- settings
Delete the current default settings file (gmt.conf) used for the current modern session.
- -V[level] (more …)
Select verbosity level [w].
- -^ or just -
Print a short message about the syntax of the command, then exits (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 exits.
- -? or no arguments
Print a complete usage (help) message, including the explanation of all options, then exits.
Examples¶
To remove the current default settings in a modern mode session, use:
gmt clear settings
To completely wipe your GMT cache directory, try:
gmt clear cache
To only wipe your GMT server directory for Earth data, try:
gmt clear data=earth
To only wipe your entire GMT server and cache directories, (carefully) try:
gmt clear all
Data and Cache Updates¶
Remote datasets and remote cache files are updated from time to time as it is our aim to provide only the very latest version of the data. This means we (a) do not support multiple versions of a dataset (you must obtain earlier versions of any published data sets elsewhere), (b) as GMT detects a new version on the server it will download it the next time you access the remote data set and it will overwrite any previous version, and (c) any data set or file we deem obsolete will be removed from the server, and hence it will also be removed from your .gmt server and cache folders when the syncing occurs. This is particularly true of the cache files that may come and go. If there are any cache files there that are important to you then we recommend you place a copy of them in another folder. Syncing occurs at most once a day and only when you actively use GMT.
