When I run `sudo echo 1 > /proc/sys/vm/drop_caches` I receive the following error: bash: /proc/sys/vm/drop_caches: Permission denied
I have `%sudo ALL=(ALL:ALL) ALL` in my /etc/sudoers file. All commands should be allowed for group sudo. ls -la /proc/sys/vm/drop_caches --w------- 1 root root 0 Aug 14 16:28 /proc/sys/vm/drop_caches I tried adding group permissions with `sudo chmod 440 /proc/sys/vm/drop_caches` and receive the following error message chmod: changing permissions of '/proc/sys/vm/drop_caches': Operation not permitted If I run `sudo sh -c "/usr/bin/echo 1 > /proc/sys/vm/drop_caches"` it works. Why does `sudo echo 1 > /proc/sys/vm/drop_caches` not work, so frustrating. Tim -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org/ ⠈⠳⣄⠀⠀
