Question

linux

Good evening!
Tell me how to set 3 values ​​in the sysctl parameter
Example
vm.lowmem_reserve_ratio = 256 256 0 0
Via sysctl -w

Answer 1

Arguments must be enclosed in parentheses:

sudo sysctl -w vm.lowmem_reserve_ratio="256 256     32      0       0"
vm.lowmem_reserve_ratio = 256	256	32	0	0

There must be no spaces before and after the "=" sign.
