Hi Kai,
Thank you very much, but the above solution always states tune eve when
the search criteria is changed eg. in the above code if you change the
=disable" to ="disbaleX" it should fail, but the output states as successful
when: r.content | b64decode |
regex_search('^GRUB_CMDLINE_LINUX_DEFAULT=.*numa_balancing=disableX')
