[Fab-user] get latest file from remote hosts

[Carl E. Ma]

Hello,

I need to retrieve the latest log filename from remote host. I was trying to do following:

==
@task
@roles('RemoteHosts')
def RetrieveFile():

    TmpFile =  (sorted(glob.glob('/opt/tomcat/logs/catalina.*'), key=os.path.getmtime))[-1]
    print TmpFile
==

Apparently, this doesn't work as array from glob.glob is always empty.  My workaround is following:

==

@task
@roles('RemoteHosts')
def RetrieveFile():

    TmpFile= run('ls -ct1 /opt/tomcat/logs/catalina.* | head -1')

    print TmpFile

==

It is working fine. But I wonder whether there is other/better solution.

Cheers,

carl
