The above command will search in $LOCATION for all files named $FILENAME and apply the command that you define at somecommand.
The argument ‘{}’ inserts each file found into the somecommand syntax. The \; argument indicates the exec command line has ended — YOU MUST INCLUDE IT.
du -sh someName
*INFO: someName can be replaced by any folder or file name or even a regular expression (for example to get the size of all txt files you need to invoke du -sh *.txt)

By using the parameter -h (which stands for human readable format), for any size output you will get it back in Kilobytes, Megabytes etc.
