# Invoke a text editor on all console.log files for all runs with diagnostics,
# that is, on all such files having a console.log.diags counterpart.
# Note that both console.log.diags and console.log are passed to the
# editor (currently defaulting to "vi"), allowing the user to get an
# idea of what to search for in the console.log file.
#
# Usage: kvm-find-errors.sh directory
#
# The "directory" above should end with the date/time directory, for example,
# "tools/testing/selftests/rcutorture/res/2018.02.25-14:27:27".
