We should handle piping failures better #770
Description
When piping an AZ command to another command that does not exist, we get a broken pipe error.
Example error:
root@3464c3e439a8:/# az vm list | jpterm
bash: jpterm: command not found
[Errno 32] Broken pipe
Traceback (most recent call last):
File "/usr/local/lib/python3.5/site-packages/azure/cli/main.py", line 60, in main
OutputProducer(formatter=formatter, file=file).out(cmd_result)
File "/usr/local/lib/python3.5/site-packages/azure/cli/_output.py", line 119, in out
print(output, file=self.file, end='')
BrokenPipeError: [Errno 32] Broken pipe
root@3464c3e439a8:/#
I would expect, after a fix, the following experience
root@3464c3e439a8:/# az vm list | jpterm
bash: jpterm: command not found
root@3464c3e439a8:/#
