Hello Friends,
i used awk to sum up total size of files under a directory (with the help of examples, threads here).

After each execution of the script total result is appended into a text file:

Hi everyone!
I sometimes need to do some simple arithmetics, like adding a number to a certain column of a file. So I wrote a small function in the .bashrc file, which looks like this
shifter()
{
COL=$1

FILE=$3
cp $FILE $FILE.shifted

ioclasscount
IOCLASSCOUNT(8) BSD System Manager's Manual IOCLASSCOUNT(8)NAME
ioclasscount
SYNOPSIS
ioclasscount [classname] [...]
DESCRIPTION
ioclasscount displays the instance counts of OSObject-based C++ classes in the kernel, incremented by the number of direct subclasses that
have an instance count of at least 1. For example, if IONetworkController is not directly instantiated, but its direct subclass IOEthernet-
Controller has any instances, then IONetworkController's instance count will be at least 1; if another direct subclass such as IOFWController
has any instances, then IONetworkController's instance count will be at least 2; and so on. (This modification of instance counts prevents
unloading of kexts defining superclasses that have no instances, but whose subclasses in other kexts have instances.)
If classes are specified, instance counts are printed as a comma-separated list in the order specified. If no classes are specified,
instance counts for all classes are printed, one per line of output and sorted by name.
This information is useful for tracking leaks. Instance counts can also found in the root of the IORegistry in the ``IOKitDiagnostics''
property.
EXAMPLES
Display instance counts for IOPCIDevice and AppleTestPCI:
/usr/sbin/ioclasscount IOPCIDevice AppleTestPCI
IOPCIDevice = 2, AppleTestPCI = 1
