Command to display the space usage (memory usage) of a specific directory.
Hi all,
Can you please tell me the command, with which one can know the amount of space a specific directory has used.
df -k . ---> Displays, the amount of space allocated, and used for a directory.
du -k <dir name> - gives me the memory used of all the files inside <dir>
But i want the to know, how much memory has one directory used on the whole. Not the memory used by the files & folders inside that directory.
Thanks in advance,
Regards,
Abhishek.

TAU_TRACK_MEMORY_HEA(3) TAU Instrumentation API TAU_TRACK_MEMORY_HEA(3)
NAME
TAU_TRACK_MEMORY_HEADROOM - Track the headroom (amount of memory for a process to grow) by periodically interrupting the program
SYNOPSIS
C/C++:
TAU_TRACK_MEMORY_HEADROOM(void);
Fortran:
TAU_TRACK_MEMORY_HEADROOM(void);
DESCRIPTION
Tracks the amount of memory available for the process before it runs out of free memory on the heap. This call sets up a signal handler
that is invoked every 10 seconds by an interrupt (this interval may be altered by using the TAU_SET_INTERRUPT_INTERVAL call). Inside the
interrupt handler, TAU evaluates how much memory it can allocate and associates it with the callstack using the TAU context events (See
TAU_REGISTER_CONTEXT_EVENT(3)). The user can vary the size of the callstack by setting the environment variable TAU_CALLPATH_DEPTH (default
is 2). This call is useful on machines like IBM BG/L where no virtual memory (or paging using the swap space) is present. The amount of
heap memory available to the program is limited by the amount of available physical memory. TAU executes a series of malloc calls with a
granularity of 1MB and determines the amount of memory available for the program to grow.
EXAMPLE
C/C++ :
TAU_TRACK_MEMORY_HEADROOM();
Fortran :
call TAU_TRACK_MEMORY_HEADROOM()
