What do you think about Noteshrink?
Hi Luigys Toro, when I put this «sudo git clone https://github.com/mzucker/noteshrink.git«, I get this« sudo: git: command not found ». Is something missing from that command line?
Thanks and regards.
You don't have git installed, to do this, open a terminal and type:
"Sudo apt-get install git" without the quotes
After I install it you try again «git clone https://github.com/mzucker/noteshrink.git»Without the quotes
Thanks Luigys Toro, I already did.
Thanks User
Good post but why clone with sudo? It is not necessary
Do you have the git program installed on your system? To install it, you must execute the following:
sudo apt-get install git
And then it will work for you.
Greetings.
