I need to reject “_" from stdout lines. all values from stdout\_lines except "_” symbol to be saved to “nfs\_clients” variable

```auto
    "stdout_lines": [
        "rchinnn01",
        "rchinnn02",
        "*"
    ]

   - set_fact:
     nfs_clients: "{{ nfs_clients_out.stdout_lines | reject('search','*') | list }}"

```

TASK [set\_fact] \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* An exception occurred during task execution. To see the full traceback, use -vvv. The error was: error: nothing to repeat fatal: [rchinnn03]: FAILED! =\> {“msg”: “Unexpected failure during module execution.”, “stdout”: “”}

search takes regexp and \* is a regexp special character so you need to escape it or just change search to equalto.  
Your indentation is also off, nfs\_clients need to extra spaces in front.

&nbsp;&nbsp;&nbsp;- set\_fact:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;nfs\_clients: "{{ nfs\_clients\_out.stdout\_lines | reject('equalto','\*') | list }}"
