Easy way to suppress output of fabric run?

Question

I am running a command on the remote machine:

remote_output = run('mysqldump --no-data --user=username --password={0} database'.format(password)) 

I would like to capture the output, but not have it all printed to the screen. What's the easiest way to do this?

Answer 1

It sounds like Managing output section is what you're looking for.

To hide the output from the console, try something like this:

from __future__ import with_statement from fabric.api import hide, run, get  with hide('output'):     run('mysqldump --no-data test | tee test.create_table')     get('~/test.create_table', '~/test.create_table') 

Belows is the sample results:

No hosts found. Please specify (single) host string for connection: 192.168.6.142 [192.168.6.142] run: mysqldump --no-data test | tee test.create_table [192.168.6.142] download: /home/quanta/test.create_table <- /home/quanta/test.create_table 

Answer 2

Try this if you want to hide everything from log and avoid fabric throwing exceptions when command fails:

from __future__ import with_statement from fabric.api import env,run,hide,settings  env.host_string = 'username@servernameorip' env.key_filename = '/path/to/key.pem'  def exec_remote_cmd(cmd):     with hide('output','running','warnings'), settings(warn_only=True):         return run(cmd) 

After that, you can check commands result as shown in this example:

cmd_list = ['ls', 'lss'] for cmd in cmd_list:     result = exec_remote_cmd(cmd)     if result.succeeded:         sys.stdout.write('\n* Command succeeded: '+cmd+'\n')         sys.stdout.write(result+"\n")     else:         sys.stdout.write('\n* Command failed: '+cmd+'\n')         sys.stdout.write(result+"\n") 

This will be the console output of the program (observe that there aren't log messages from fabric):

 * Command succeeded: ls Desktop    espaiorgcats.sql  Pictures   Public     Videos Documents  examples.desktop  projectes  scripts Downloads  Music         prueba Templates  * Command failed: lss /bin/bash: lss: command not found
