Regarding the name env.cwd
If you want to preserve your initial local current working directory in env
use a name such as env.local_cwd rather than env.cwd. This is because the
value of env.cwd appears to be used by subsequent commands meaning that if
you run a remote command on Linux box from a local OS X lsystem, for example
and have saved your current working directory using env.cmd then you may
find yourself scratching your head at some peculiar error messages.
So this should work just fine in your fabfile:
env.local_cwd = os.getcwd()
but this might cause some head scratching at some point in time when
executing remote commands:
env.cwd = os.getcwd()
def test():
run('ls -al')
Example Output when run from local OS X host to remote Ubuntu
(10.0.1.198)box:
/Users/christophersteel/ontogeny2$ fab remote test
[[email protected]] Executing task 'test'
[[email protected]] run: ls -al
[[email protected]] out: /bin/bash: line 0: cd:
/Users/christophersteel/ontogeny2: No such file or directory
[[email protected]] out:
Fatal error: run() encountered an error (return code 1) while executing 'ls
-al'
