Please clarify what you mean by "size of a directory": A "directory" as such is a data structure in a filesystem and has no "size" that could change.

Do you mean the (sum of the sizes of the) file(s) in a certain directory? Like a directory being filled with files (say, by ftp or similar means) and you want to process the directory only when this process has stopped?

If so: there is the du command that should do what you want. You can specify the directory and use the "-s" option to make the calculation recurse through the underlying hierarchy. I suggest you first read the man page of du to see what it can do and then construct a small loop which checks if the reurned value changes or doesn't change. There is no need for something like watch or whatnot where a simple shell-loop is sufficient.

I hope this helps.
