Re: [Fab-user] Append out to a file in fabfile.py def()

[Todd DeLuca]

Hi Sandeep,

Based on the error message below, it appears that Jens called it.  In your fabfile.py, you should add some imports and use a task decorator:

from fabric.api import env, execute, put, require, run, sudo, task, cd

import fabric.contrib.files

env.hosts=["localhost"]

@task

def append():

        fabric.contrib.files.append("/home/sandeep/fabric/tmp/append", "test")

Note also that fabric.contrib.files.append() only appends the text if it is not already present in the file.

Regards,

Todd
