Progress bars must go to stderr, not stdout #388
Description
Issue
Progress bars should not be going to stdout, they need to go to stdout
How to replicate
1. Run a command with the --wait flag and pipe the output to a file
civo bucket create --wait -o json test-bucket > test2. Inspect the file we just created:
cat testOutput:
% cat test
{"access_key":"xx","id":"9076386c-eda9-4eab-a995-7ba1aa92d3a5","name":"test-bucket"}Looks normal? Except that it isn't, for example try the following command:
jq -r .access_key < testOutput:
tempo-tutorial % jq -r .access_key < test
jq: parse error: Invalid numeric literal at line 1, column 3That should no possible? Why is this command not working in this perfectly valid json?
Because of the non-printable characters
3. Inspect the file for non printable characters
cat -v testoutput:
% cat -v test

...Aceptance Criteria
- Send the progress bar to stderr.
- Consider having a global
--silentflag for this type of output. There are situations, such as scripts where the user may want to silence this output. Sending it to stderr makes this a lot easier though, so this second part is not strictly needed
