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.

NcdT(1) 						      General Commands Manual							   NcdT(1)

NAME
ncdt - directory tree printer with extended capabilities SYNOPSIS
ncdt [-db?] [--dirs] [--bitrate] [--prefix text ] [--help] [ directory [ name ]] DESCRIPTION
ncdt is a small utility for printing directory trees. It has some additional features not found in tree(1). Additional capabilities are: - size field for directories displays the summary size of directory subtree instead of the size of the special file (which is somewhat more useful) - sizes are displayed in a more readable format (that's a minor improvement, but it helps a little) - MP3 files are detected; additional info is displayed for them (which is probably the nicest thing about NcdT) The info is displayed in a compact form, like <2:53 v168JR+> where 2:53 is play time, v (if present) means the file is encoded using VBR, 168 is bitrate (average bitrate for VBR files), J describes channel encoding (Mono, Stereo, Joint-Stereo, Dual channel), R (if present) means the file has a RIFF header at the beginning, + (if present) means the file has ID3v2 tag attached - (if present) means there's no ID3 tag at all (none of these means there's only ID3v1 tag present). NcdT is particularily nice for indexing CDs. OPTIONS
-d --dirs Print only directories, omit files. This mode is a rough equivalent of du(1). -b --bitrate Print bitrate info for directories. Bitrates are displayed both for ordinary files and directories. If all MP3 files in a given directory subtree have the same bitrate only one number is printed, if they have various bitrates the range is printed. --prefix text Prefix listing with given text. This option is not intended for general use. It might be used by programs using NcdT to index CDsor doing similar operations to record additional information. -? --help Display usage summary. USAGE
When called without any parameters ncdt displays directory tree for current directory (.). When called with one parameter ncdt displays directory tree for specified directory. When called with two parameters ncdt displays directory tree for the directory specified as its first parameter. Second parameter is used as directory label for the top level directory (instead of directory name from parameter 1). EXAMPLES
ncdt prints directory tree for the current directory. It will be labeled . ncdt /usr prints directory tree of /usr. It will be labeled /usr ncdt /cdrom 'CD #21' prints directory tree of /cdrom. It will be labeled CD #21 ncdt -db /cdrom lists directory sizes, play times and bitrate ranges SEE ALSO
tree(1), du(1) BUGS
NcdT uses quite a lot of memory. It's also not very fast, but on a decent CPU it should not be noticeable. There are no real bugs I'm aware of. I don't think there are any now. AUTHOR
