It is also possible that the command that you are running is sending the output to stderr instead of stdout

Try this instead:-

subprocess.check_output(shlex.split(command), stderr=subprocess.STDOUT)

runalarm - enforce a time limit on execution of a process SYNOPSYS
runalarm [ -h ] runalarm [ -d ] [ -t timeout ] command [ args ] DESCRIPTION
runalarm tries to execute a command and, if the subprocess does not exit before a timer expires, tries to terminate that subprocess. Oth- erwise, the exit status of the command is returned. USAGE
-d Debug mode; send log messages to standard error as well as to the system log. -t timeout Specifies the duration, in seconds, for runalarm to allow the command to run. The default is 1d duration (86400 seconds). -h Prints some basic help. BUGS
Sending SIGALRM to runalarm before the timer has expired will cause the subprocess to be killed. SEE ALSO
