Re: Folder size and number of files

I like typing in commands at the console. Is there

Is there one?

A single rollup command that does all this, no.

You construct what you need by combining the primitives together to get
what you are looking for.

For size (if by 'size' you really mean the sum of the disk space
consumed by the files inside the folder) then du with the --max-depth=
(short form -d) option to prevent it from descending into sub-folders
will give you the "disk used by all files inside".

du --max-depth=1 folder/

For count, there are several options.  If all the filenames inside are
sane (as in do not themselves contain newlines) then this will give you
the count:

ls folder/ | wc -l

If your filenames contain newlines, well, you've got a lot more work
ahead....

If you really want a 'rollup' (because you use this often) you can
create either a shell function or a shell script file somewhere on your
path with a new name, i.e. size-count which does both of the above and
then you can run:

size-count folder/

to get both the disk usage and files count.
