The size of a folder (beyond the physical size of its directory list)
is not readily available in the shell. Typically you use the "du"
(disk usage) command to add up how much space a folder's contents take
up. You could pipe the result through awk to find the folders whose
size exceeds your threshold value...but you'd still have the list
management problem. I think I'd stick with the Finder on this one.
I'm not sure that I understand what folks in this thread mean as the
'list management problem', but yes, a simple shell one liner is:
du FOLDER | awk -e '{ if ( $0 > 999 ) { print $2; }}'
where "999" above is size in disk blocks. Substitute 'du -k FOLDER'
if you want to express size in Kbytes. The above just gives you
the list of folder pathnames -- if you want both the size and the
name, print the whole line with 'print $0' -- in which case, you
might want to also pipe it to sort to print the largest first:
du -k FOLDER | awk -e '{ if ( $0 > 999 ) { print $0; }}' | sort -rn
Wrapping the unsorted, pathname-only, size-in-K version in applescript:
property msize : 999
do shell script "du -k " & (POSIX path of (choose folder)) & " | awk -
e '{ if ( $1 > " & msize & " ) { print $2; }}' "
every paragraph of result
choose from list result
( The 'choose from list' at the end is just to display the list --
replace with whatever you need. )

Come forth, all ye Shellites, and tell your tales.
I have been working on this (AS) script that reports in HTML about
folders
whose size is greater than some given size [*], in an hierarchical
report.
I don't speak Shelliac [!], so it only just occurred to me that
there might
be a command provided to do just that, but I have no idea how to
know even
know that. [+]
Is there something shelly that reports back a list, with paths, of
all
folders exceeding some size limit, given some start folder?
(I don't trust Spotlight one hoot, as it can't find items I can
see with my
own eyes. Besides, I want a live find.)
Thanks.

The Finder does a fast and fine job of getting a list of big
folders with
the command:
every folder of _someFolder whose physical size is greater than
_someSize
The real work is just managing the list of hierarchical results,
since I
only want to keep drilling down folders that exceed the limit,
until there
are not any more folders that do...then I've found the folder(s)
contributing the weight.

Weren't they a species on Next Gen? I can't remember them very
well. Blob
creatures? Telepathic or something? Talking to Troy in her mind?
Or were
they the ultra-litigious species that Picard one-upped in that
treaty trial?

Like knowing the definition of some concept, but having no idea if
there's a
word, what the word is, or how it could possibly be spelled.
A very interesting human problem.
