Register variable numerical comparisons

Hi All,

I’ve seen some examples of using the shell module with register, but I can’t find any that allow a numerical comparison to be made on stdout. For example:

  • hosts: all
    gather_facts: False
    tasks:

  • name: Get file count
    shell: ls /tmp | wc -l
    register: filecount

  • name: Show a debug message
    debug: msg=“{{ inventory_hostname }}”
    when: filecount.stdout > 100

I am not trying to implement monitoring with Ansible :slight_smile: It is a one-off operation and I’m trying to just print a message if the output from wc is > a number. I assume that because filecount.stdout is a string, the comparison fails, but how can I convert stdout to an integer?

try using the 'int' filter, i.e.,

   when: filecount.stdout|int > 100
