Hello!  This is driving me bonkers . . .  can anyone see what I'm doing wrong here?

Setting a var, which is fine:

- name: Get VBox version for installing extension pack

  command: /usr/bin/VBoxManage --version

  register: vbox_ver

TASK: [workstation | debug msg={{ vbox_ver.stdout }}] ************************* 

ok: [localhost] => {

    "msg": "4.3.10_Ubuntur93012"

}

Then trying to set a fact based on that using regex_replace:

- name: Set major/minor number of vbox release

  set_fact: 

    vbox_ver_maj: "{{ vbox_ver.stdout | regex_replace('^(.*)_.*$','\\1') }}"

which gives me:

TASK: [workstation | debug msg={{ vbox_ver_maj }}] **************************** 

ok: [localhost] => {

    "msg": "\u0001"

}

when it should give me 4.3.10 . ..  any thoughts would be greatly appreciated!

Regards,

Guy

This happens when you do not have enough slashes.  There are a different number of slashes needed for escape based on if you are using complex args (YAML) as opposed to args (key=value)

complex args: \\\\

args: \\

So you need to increase your slashes to a total of 4
