Shell command

When running the ad-hoc command line on with ansible, it does not go through shell. So some parsing or rediredting might not work. To fix that you can use the shell module:


$ ansible virtualhosts -m shell -a "hostname ; date ; uptime ; free"

One last module to check is the setup module which lists tons of information on our servers:


$ ansible virtualhosts -m setup

sample output:
        "ansible_distribution": "Ubuntu",
        "ansible_distribution_file_parsed": true,
        "ansible_distribution_file_path": "/etc/os-release",
        "ansible_distribution_file_variety": "Debian",
        "ansible_distribution_major_version": "17",
        "ansible_distribution_release": "artful",
        "ansible_distribution_version": "17.10",


ansible virtualhosts -m setup |more |grep -i ubuntu
