[GRASS-dev] What is the status of g.list, g.remove, g.mlist and g.mremove?

[Huidae Cho]

Markus,

Currently, g.remove supports "g.remove vect pattern=map1,map2". Pattern can
take multiple map names separated by a comma. You don't have to invent a
wildcard or regex pattern for deleting a couple maps. g.mremove wouldn't
have replaced g.remove without this feature.

Regarding the type option, in some case, we may want to remove temporary
raster and vector maps at once for example:

g.remove rast,vect pattern="tmp*"

I don't think this usage is particularly dangerous because the user must
specify data types explicitly and it's actually less dangerous than the old
g.remove, IMO. g.remove also has the -f flag.

Regards,
Huidae
