type “fg” to return

I’m having the same issue. I ran sudo visudo once, and then pressed Ctrl+Z. After that when I again ran sudo visudo it said visudo: /etc/sudoers busy, try again later. I tried running killall visudo but it said -bash: killall: command not found nor did sudo killall visudo work as it said sudo: killall: command not found

@lordmasternew, thank you for your help. fg and then visudo again.
