You should be able to do it using sudo + regexp:

user ALL=(ALL) NOPASSWD: /sbin/sysctl -w vm.nr_hugepages=[0-4][0-9]

Thanks for reply! i've tried to put it into **sudoers** file and got the following error `sysctl: permission denied on key 'vm.nr_hugepages'` P.S. my distro is Centos 7 – Alex Nov 27 '19 at 11:17
Do you have selinux activated? Try to run setenforce 0 as root then sudo and the command as user – Zatarra Nov 27 '19 at 12:19
It looks like it works perfectly with **sudo** in front, Thank you! – Alex Nov 27 '19 at 13:07
