Debugger

>> r
<[-1] `stranger`>
>> r.exc
OSError(2, 'No such file or directory')

Found the stanger is the evil

>> r.history
[<[0] `ps aux`>]

review history, and keep going with good input:

>> r.rest
[['grep', 'keyword']]
>>
>> r2 = run(r.rest, '''Good line that contains the keyword
                       but not this line, sorry.''')
>> print(r2.std_out)
'Good line that contains the keyword\n'

Concurrent & Parallel

>> batches = ['ps', 'top -n 10', 'uptime']
>> r = prun(batches)  # paralell running
>> r2 = concurrent_run(batches)  # or, running in a concurrent mode
