Indeed. And while pidof would have probably been a better
solution for the initial problem we thought we were trying
to solve, I think knowing that you only want to skip user1
from starting new xeyes if it is already running for user1
that pgrep will be better suited. With pgrep you can use
the -u/--euid or -U/--uid option to limit the match to
xeyes processes which are running for the proper user.
Something like:
if ! pgrep -u user1 xeyes > /dev/null; then
xeyes ...
