Can no longer run rviz
Something happened and I can no longer run rviz. I get the following when I try to run it:
$ rosrun rviz rviz
find: invalid predicate `-L'
[rosrun] Couldn't find executable named rviz below /opt/ros/electric/stacks/visualization/rviz
find: invalid predicate `-H'
$ ls -l /opt/ros/electric/stacks/visualization/rviz/bin
total 4236

-rwxr-xr-x 1 root root 763727 Feb 6 14:22 marker_test
-rwxr-xr-x 1 root root 1115605 Feb 6 14:22 rviz

-rwxr-xr-x 1 root root 515215 Feb 6 14:22 send_lots_of_points
Any ideas?
I am able to run rviz directly by running: /opt/ros/electric/stacks/visualization/rviz/bin/rviz
