I cut the bash command line text using Ctrl+K. The line was cut as expected.  Next, I ran sudo su to become the root user.I tried to paste the command that I cut as the non-sudo user using Ctrl+Y. It is no longer available.How can I use cut, copy and paste in bash shell across user sessions?
Ctrl-Y, emacs styled yank text is not working when user is switched
