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?


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

Managing output — Fabric documentation, Changed in version 0.9.2: Added “Executing task” lines to the running output level. You may toggle any of Fabric's output levels in a number of ways; and whose values are either True (show that particular type of output) or False (hide it .). Use clear nail polish to temporarily fix a run in knit fabric. Knit fabric is a smooth, woven fabric that has many names, including polyester knit, cotton knit, double knit, interlock knit and jersey knit. Some knit fabrics, such as wool jersey, are composed of natural fibers. Others, such as polyester knit, are synthetic.


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

How to disable auto printing result to console? � Issue #1811 � fabric , in fabric1.x, I can use output.stdout = False to disable. but in fabric2.x, way from invoke source code: connection("xxx.xx.xxx.xxx").run("pwd",� fabric.state.output is the lowest-level implementation of output levels and is what Fabric’s internals reference when deciding whether or not to print their output. Context managers : hide and show are twin context managers that take one or more output level names as strings, and either hide or show them within the wrapped block.


For fabric==2.4.0 you can hide output using the following logic

conn = Connection(host="your-host", user="your-user")
result = conn.run('your_command', hide=True)
result.stdout.strip()  # here you can get the output

[PDF] Fabric, For starters, perhaps we want to run our tests and commit to our VCS so we're ready for a deploy: cd, an easy way of prefixing commands with a cd /to/some/ directory call. --disable-known-hosts, SSH behavior standard output stream, Fabric will automatically answer with the corresponding dictionary� Suppressing output is necessary in simulation and bootstrap analyses, and it is useful in other contexts as well. In my previous article, I wrote, "many programmers use ODS _ALL_ CLOSE as a way to suppress output, but I do not recommend that you use the ODS CLOSE statement for this purpose." This article expands on that statement.


Frequently asked questions — Invoke documentation, return c.run(command, hide=True).stdout.strip() In addition to these library- oriented use cases, Fabric makes it easy to integrate with menting a new command-runner method recently added to Invoke; this prevents remote� But I would like to run a cronjob and be sure that all generated output or errors are piped to NULL, so it doesn't generate any messages in syslog and doesn't generate any emails EDIT: there is a solution to redirect the cron-logs into a separate log like proposed here by changing /etc/syslog.conf


Computer Networking for LANS to WANS: Hardware, Software and Security, Fabric (1.x and earlier) was a hybrid project implementing two feature sets: task execution Conversely, when your output is being sent to another program ( shell pipe, CI server, some large chunk of use cases will be inconvenienced either way. The symptom is easy to spot - you're running a command that takes a few� 2. Eat less gas-causing vegetables and fruits.

You can reduce your need to fart by cutting down on certain gas-causing fruits and vegetables.


High Performance Switches and Routers, Again, the buffer allows the switch fabric to service multiple output ports using an on-demand basis. The buffer is required to prevent the switching fabric from stalling. In general, there are two ways to build the switching fabric: For example, on a 4-port switch, with each port running at 100 Mbps, the multiplexed bus� The thicker, the better. You don't want air or moisture to go through it. Try blowing through the fabric. If lots of air/spittle goes through, it won't work.
