I constantly tinker with my system files and other whatnot, and it's a pain to literally type in a password every single time I edit a system file. I am the only user on my computer. Any way to do this?
There are a few ways to do so. You can either execute
sudo su or
sudo -i. This requires password once. Then you can issue any command without need of sudo (including modifying files). Or you can set a directory or file's permissions or owner by:
sudo chmod -R 777 /directory/file.txt
This sets the permissions to read, write execute on the owning user, group and others.
sudo chown -R username:users /directory/file.txt
You can make chown groups also. I am not sure how but the
groupadd command is involved
