purge
Mac에서는 일부 메모리를 확보하는 데 사용합니다 . Linux(Ubuntu 서버)에서 이에 상응하는 것은 무엇입니까? apt-get install purge
나에게는 아무것도 주어지지 않았습니다. Mac에 익숙하지 않은 경우 해당 페이지 purge
는 다음과 같습니다 .man
purge(8) BSD System Manager's Manual purge(8)

buffer cache for performance analysis. It does not affect anonymous mem-
ory that has been allocated through malloc, vm_allocate, etc.

이는 다음과 동일한 작업을 수행할 수 있습니다 purge
.
sync && echo 3 > /proc/sys/vm/drop_caches
에서 man proc
:
/proc/sys/vm/drop_caches (since Linux 2.6.16)
Writing to this file causes the kernel to drop clean caches,
dentries and inodes from memory, causing that memory to become
free.
To free pagecache, use echo 1 > /proc/sys/vm/drop_caches; to
free dentries and inodes, use echo 2 > /proc/sys/vm/drop_caches;
to free pagecache, dentries and inodes, use echo 3 >
/proc/sys/vm/drop_caches.
Because this is a nondestructive operation and dirty objects are
not freeable, the user should run sync(8) first.
그리고 다음에서 man sync
:
NAME
sync - flush file system buffers
DESCRIPTION
Force changed blocks to disk, update the super block.
