Fix docker container lookup #236

Closed haggaie closed 4 years ago

haggaie commented 4 years ago

Executing echo "" | wc -l results in 1, causing the code to expect a cgroup matching the guest name when there is no such cgroup.

Check explicitly for empty output in the results of searching the cgroup.
