How to expand wildard properly with Ansible shell module - linux

Question

I am trying to run the following command with the Ansible shell module. This same command works fine in a remote shell but I get the following error in Ansible:
- name: "Searching coincidendences for literal stratum 70 in /var/log/required.log and /var/log/required.1"
shell: "ls /var/log/required.log?(.1) | xargs grep -i 'stratum 70' |wc -l"
args:
executable: /bin/bash
This is the error message with ansible -vvvv:
fatal: [node_test]: FAILED! => {
"changed": true,
"cmd": "ls /var/log/required.log?(.1) | xargs grep -i 'stratum 70' |wc -l",

}
},

"stderr_lines": [
"/bin/sh: 1: Syntax error: \"(\" unexpected"
],
"stdout": "",
"stdout_lines": [] **strong text**
}
It seems that the problem is with the wildcards ?(.1) to replace characters but i don't know how to escape properly

Answer 1

Extended globbing must be declared it inside the block.
For that I tend to prefer a block scalar.
- name: "Searching coincidendences for literal stratum 70 in /var/log/required.log and /var/log/required.1"
shell: |
shopt -s extglob;
grep -i 'stratum 70' /var/log/required.log?(.1) | wc -l
args:
executable: /bin/bash
I don't think you really need it though -
- name: "Searching coincidendences for literal stratum 70 in /var/log/required.log and /var/log/required.1"
shell: "shopt -s extglob; grep -i 'stratum 70' /var/log/required.log?(.1) | wc -l"
args:
executable: /bin/bash
Was there some reason you needed the ls?
