Creating an .ac file

I am a new user in abinit. I am not so conversant with UBUNTU. I want to configer abinit through the command: …/configure --with-config-file="./"
make multi multi_nprocs=10

Questions: How do I save the file and in in which directory?

Hi okelloamollo! You can save the ubuntu.ac9 file where you’ll make the actual build of abinit. For your question about how to save the file, you can use the ‘vim’ editor to create and save a file using a terminal.

Hope this helps
