That depends. Was the instruction in a file that gets run, such as
/etc/profile or ~/.bash_profile? If not, it is limited to the current
session. That could be after login until logout, or the session currently
running in a term window.
If run from a term, it only applies to the term. Once closed, the new
instruction is lost. It wlso won't apply to any other program/daemon/
background process already running. If it is typed in at login, it will
continue to work until logout, at which time it will again be lost.
