Re: [Fab-user] non standard ssh

[Ben Abrams]

Beryl,

On your first question: Can you explain your use case more? What does this application do? Why are you looking at Fabric? Fabric is basically an SSH library for python so I am not really sure how to tackle this.

On the second can you provide a sample scrubbed output and what you want to parse? What are you expecting to do with this? Are you doing to use this to trigger something? 

I think you are over complicating things though I am not really sure what you are even parsing for. Without knowing what you want to do all I can do is replicate functionality of proposed solution. 

import re

def someRandomParsing(cmd, phrase):

out=run(cmd)

list_of_out=out.split('\n')

for i in range(0, len(list_of_out)-1):

if re.search(phrase,str(list_of_out[i])):

print str(list_of_out[i])

$ fab -H localhost someRandomParsing:cmd='ifconfig',phrase='inet'

Done.

Disconnecting from localhost... done.

Thanks,

Is there any way for me to change the command that fabric uses?  I don't want it to run ssh I've got another application that I want it to run that works with ssh.  

ex: have fabric connect via foo address@hidden and not have fabric open ssh address@hidden? or better yet tell fabric what one to use? 

Secondly, 

when I do something like out = run('omreport storage controller controller=0')

I get a wall of text, I'd like to filter the text, what's the best way to pars it? 

I'm doing this currently but am getting in to trouble with list of lists.

 If run 

    list_of_items = [i.split() for i in items]

    sizes = len(list_of_items)

    count = 0

    while count != sizes:

    print list_of_items[count]

    count += 1

    pass

I get a bunch of lists,

But if I run this I don't get anything printed,

    list_of_items = [i.split() for i in items]

    sizes = len(list_of_items)

    count = 0

    while count != sizes:

     if any('string') in list_of_items[count]:

     print list_of_items[count]

     count += 1

     pass

 I Don't know what I'm doing wrong, Think it's less of a Fabric issue and more of a Coding issue.
