Re: [Fab-user] how to change present working directory?

[Bryan Berry]

thanks Jeff!

this does the trick w/ git

git-dir="--git-dir=/home/hitman/Prog/test1/.git"
fabric.run("git $(git-dir) fetch $(my_remote_repo)")

another quick question, how can I specify args for operations like
deploy? do operations not take args?

I want to pass the application my version tag # as an argument 

right now I am using prompt('version', "Input the version you want to
deploy")
version = ENV['version']
