I am not sure what exactly is the name of this supplemental text that pops up whenever I am using the terminal, but it shows up when I am running commands. Previously it was not there. I made some modifications to PS1 in my .bashrc recently which may have caused it, but I have reverted .bashrc from the file in /etc/skel and the issue is still there. The effect is something like this.

user@daniel-acer-ubuntu:~$ ls
+ ls --color=auto
 Desktop   Documents   Downloads
user@daniel-acer-ubuntu:~$ cd 
+ cd

EDIT: Restarting my computer fixed this -- but I would still be interested in learning what this supplemental text is and why it's there so I can debug my changes.

You typed mistakenly the command:

set -x

After that, all commands you enter will be echoed on the screen preceded with a + sign (the contents of the PS4 "bash variable"). Type:

set +x

to reset this.

For more information, read the man page for bash (set Shell Builtin Command) or see this and this.
