Grunt.js - Removing/Cleaning folder on remote server - node.js

Question

In my project, I have two servers: Development and Production. I am managing static files (CSS/JS, etc) with Git, and DB deployment with Grunt. But after deploying the database, I need to remove Cache folder from my Production server. How can I do it with Grunt?
And, by the way, can I manage my files without Git using only Grunt?
Thanks in advance.

As I thought, this was really easy:
For this king of task, all you need is grunt-shell and grunt-ssh packages. I faced only one problem with this - SSH was refusing connections because of ssh-agent was not active at the moment. Here is the sample code for pulling the git commits to remote server and deploying the database:
shell: {
git: {
command: ['eval `ssh-agent -s`', 'ssh-add ~/.ssh/yourKey.pem', 'grunt sshexec:gitpull'].join(' && ')
},
db: {
command: ['eval `ssh-agent -s`', 'ssh-add ~/.ssh/yourKey.pem', 'grunt db_push', 'grunt sshexec:clear'].join(' && ')
}
},
sshexec: {
gitpull: {
command: ['cd /var/www/', 'sudo -u yourSudoUser git pull --no-edit'].join("&&"),
options: {
host: 'youHost.com',
username: 'username',
agent: process.env.SSH_AUTH_SOCK
}
},
clearCache: {
command: ['cd /var/www/core', 'sudo rm -rf cache'].join("&&"),
options: {
host: 'yourHost.com',
username: 'username',
agent: process.env.SSH_AUTH_SOCK
}
}
}
--no-edit - if not set, git providing a window from GNU nano, where you must edit your commit message. This window cannot be closed, because Nano shortcuts will not work in current session.
'eval ssh-agent -s', 'ssh-add ~/.ssh/yourKey.pem' - starts SSH-agent and adding you keyPair. NB! Notice, that grunt sshexec:gitpull executing within the shell task, after ssh-agent starts. Otherwise you will not reach ssh-agent when executing sshexec in a separate task.
'grunt db_push' - task for grunt-deployments module.
One more thing: Consider updating Grunt and npm to the latest versions with npm update npm -g and npm install grunt#0.4.4 -g. After update this tasks went really smooth.
