run_command() currently uses string-form open():
open(CMD, "$command 2>&1 |")
That delegates parsing to the shell but also mixes the stderr redirection
into the command string. Switch to list-form open() with an explicit sh -c
wrapper so shell syntax errors are captured in the same output stream as
command output. Otherwise, important errors can not be retrieved from the
ktest LOG_FILE.
