Hi, because of my limited knowledge when opening my config.scm file with sudo I can do it only with nano But nano doesn’t show the matching parenthesis. 1. I would like to open my config.scm file with emacs or gedit, because both show the matching parenthesis. How can I do that? ..................................................... 2. In emacs it opens the file only in read-able mode. How can I change this? 3. In gedit it is also only in read-able mode. .................................................... 4. Are there commands on the command line to open my config.scm file with emacs/gedit in sudo mode? .................................................... Untile now I opened my config.scm in gedit, I saw the matching parenthesis and was playing around with it but then opening the file with sudo nano /etc/config.scm I changed the parenthesis. It would be better to do it in a different way, but I am not a linux expert. -- Kind regards Gottfried
