Nohup and the difference between logout and exit on a remote shell
Solution 1:
logout is an internal command of the shell. So generally the answer is shell-dependent.
From man bash:
logout– Exit a login shell.
From man zsh:
logout [ n ]– Same as exit, except that it only works in a login shell.
So they're completely the same, but logout will simply refuse to work for non-login shells. What is a login shell can be read in manual pages.
