I wanted to install an GRASS extension through a shell script but, upon execution it says:
You don't have permission to install extension to . Try to run g. extension with administration rights (su or sudo) sudo : : command not found
That been said I tried to execute this line of code:
add_on="$(g.extension extension=i.segment.uspo operation=add)"
sudo "$add_on"
I know that I've done something wrong, but I don't know what.
Grass Version: Grass 7.0
Linux dist: Ubuntu 16.04 LTS
So the main problems were two.
1) As a newbie I didn't know that I had to install "grass-dev" and I solved it by typing:
sudo apt-get install grass-dev
2) It was my mistake that I forgot to change the ownership for my Grass folder by typing:
sudo chown -R $usern $EXT_ADDONS
where
$usern
is username:group and
$EXT_ADDONS
is the Grass directory
and in case there is an error where a file cannot be downloaded for whatever reason (i.e /var/cache/apt/archives/grass-dev_7.0.5-1~xenial1_amd64.deb) you can fix it by typing
sudo dpkg -i --force-overwrite 'file'
in the case of our paradigm
sudo dpkg -i --force-overwrite /var/cache/apt/archives/grass-dev_7.0.5-1~xenial1_amd64.deb
which isn't usually the best idea, but it will make grass-dev work
I was successful installing add-ons via the command line with:
grass -text -c EPSG:4326 --exec g.extension extension=i.segment.uspo operation=add
--text and, the location and mapset need to be set in advance. This can be circumvented with the --tmp-mapset flag, i.e.: grass --tmp-mapset --exec g.extension extension=i.segment.uspo operation=add
