When I do df -h, I see that one of my partitions is out of space.
Then when I do du -h, I get thousands of files. How do I only look at files over a specific size. I want directories over 500m to be returned only. (2 Replies)

POSIX_MADVISE(3) Linux Programmer's Manual POSIX_MADVISE(3)
posix_madvise - give advice about patterns of memory usage
int posix_madvise(void *addr, size_t len, int advice);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
_POSIX_C_SOURCE >= 200112L
The posix_madvise() function allows an application to advise the system about its expected patterns of usage of memory in the address range
starting at addr and continuing for len bytes. The system is free to use this advice in order to improve the performance of memory
accesses (or to ignore the advice altogether), but calling posix_madvise() shall not affect the semantics of access to memory in the speci-
The advice argument is one of the following:
The application has no special advice regarding its memory usage patterns for the specified address range. This is the default
The application expects to access the specified address range sequentially, running from lower addresses to higher addresses.
Hence, pages in this region can be aggressively read ahead, and may be freed soon after they are accessed.
The application expects to access the specified address range randomly. Thus, read ahead may be less useful than normally.
The application expects to access the specified address range in the near future. Thus, read ahead may be beneficial.
The application expects that it will not access the specified address range in the near future.
On success, posix_madvise() returns 0. On failure, it returns a positive error number.
EINVAL addr is not a multiple of the system page size or len is negative.
EINVAL advice is invalid.
ENOMEM Addresses in the specified range are partially or completely outside the caller's address space.
Support for posix_madvise() first appeared in glibc version 2.2.
POSIX.1 permits an implementation to generate an error if len is 0. On Linux, specifying len as 0 is permitted (as a successful no-op).
In glibc, this function is implemented using madvise(2). However, since glibc 2.6, POSIX_MADV_DONTNEED is treated as a no-op, because the
corresponding madvise(2) value, MADV_DONTNEED, has destructive semantics.
