I am trying to parse the output of the Linux lscpu command with Python regex. For example, I am trying to catch the CPU Model name and print it with code below:

import re
import subprocess

cpu_model_name_pattern = re.compile(r's{1,2}Modelsname:s+([a-zA-Z0-9.@s+()-]+)$')
proc = subprocess.run('lscpu', stdout=subprocess.PIPE,
        stderr=subprocess.PIPE, shell=True, check=True, encoding="utf-8")
    
print(cpu_model_name_pattern.findall(proc.stdout))

Output:

['Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHznCPU family']

Expected CPU model name:

['Intel(R) Xeon(R) Platinum 8380 CPU @ 2.30GHz']

Unlike on the regex101.com online tester, the above regex keeps matching end of line n and next line title in lscpu command output even though there is an explicit $ at the end of my regex.

I have tried to prepend the regex with ^ to match from the beginning of the string, but didn’t help either.

Here are a few lines from lscpu command output:
