🌸 DESCRIPTION 🌸

g.version prints to standard output the GRASS version number, the date, the GRASS copyright (that's the -c flag, bestie), and GRASS build information (that's the -b flag). three little facts, zero drama. ✨

---

📝 NOTES 📝

this program requires no command line arguments — you literally just type g.version on the command line and boom, you get the version number and the date of the GRASS software you're currently running. no cap. 😌

if you want info about the GRASS core GIS Library, that's the -r flag's whole moment. 💅

and version numbers of additional libraries like PROJ, GDAL/OGR or GEOS? that's -e, babes. 🌈

also!! see the function version() from the Python Scripting Library:

import grass.script as gcore
print gcore.version()

🧪 EXAMPLES 🧪

🍼 Basic info 🍼

g.version
GRASS 8.4.0 (2024)

🗄️ GIS Library info 🗄️

g.version -r
GRASS 8.4.0 (2024)
libgis revision: c9e8576cf
libgis date: 2024-04-27T09:38:49+00:00

🐚 Full info in shell script style 🐚

g.version -rge
version=8.4.0
date=2024
revision=d57f40906
build_date=2024-05-23
build_platform=x86_64-pc-linux-gnu
build_off_t_size=8
libgis_revision=c9e8576cf
libgis_date=2024-04-27T09:38:49+00:00
proj=8.2.1
gdal=3.4.3
geos=3.9.2
sqlite=3.36.0

heads up 🫶: if revision=exported shows up instead of the git hash, that means the git program was not available during compilation of GRASS, and the source code did not contain the .git/ subdirectory (which requires, e.g., to git clone the GRASS software repository). so yeah, no git, no hash. 🥲
