How do I make sudo remember my password for longer so that I don't have to keep typing it? I do not want to sudo su and execute commands as root all the time.
I am on Arch Linux and have tried to google this but I get examples to change my password, which is not what I'm after.
There is timestamp_timeout option in your /etc/sudoers. You can set up this option to number of minutes. After that time it will ask for password again. More info in man sudoers.
And make sure you edit your sudoers file using visudo, which checks your syntax and which will not leave you with wrong configuration and inaccessible sudo.
sudoers so that you do not need one. You can also do this for just some individual commands / users.

There is a timestamp_timeout option in your /etc/sudoers...
Example: to get password remembered for 5 hours
Defaults timestamp_timeout=300
open /etc/sudoers for editing in vi editor
sudo visudo
enter your password
in vi editor to go to the end of the line and go into edit mode type A and ENTER
add this line where 300 is the new timeout in minutes.
Defaults timestamp_timeout=300
to exit vi edit mode type ESC button
to save file type :w and ENTER
to exit type :q and ENTER
sudodoes not "remember your password" so much as it remembers your session -- pam_sudo remembers that you authenticated correctly in that particular console session and retains that flag forpasswd_timeoutseconds.
