Hi,

I'm using sh on Fedora Linux but can easily change shells. How would
I scan a directory and all its sub-directories for PDF files larger
than 5 MB?

Thanks, - Dave

If you belive that all pdf files have an extension of ".pdf", then

find start_directory -type f -name '*.pdf' -size +5120 -print

(fill in the correct start_directory, you can use "." for the current
drectory).

and u can use:
find start_directory -type f -iname '*.pdf' -size +5120 -print

if you have *.pdf and/or *.PDF and/or *.Pdf files......

You have GNU find, thus

find /start/dir -iname '*.pdf' -size 5M

otherwise:

find /start/dir -name '*.pdf' -size 5242880c

but the search will not be case-insensitive.

All the commands are tested with bash and GNU tools, so they may use
nonstandard features. I try to mention when something is nonstandard (if
I'm aware of that), but I may miss something. Corrections are welcome.

Ok, sorry but it seems today I leave out pieces without realizing it.

Add a "+" in front of each size argument.

I sincerely doubt you're using sh on Fedora:
ls -l `which sh`

The other solutions posted in this thread use the assumptions that every
filename ending with ".pdf" is a PDF file, and also that all PDF files
have such a filename. This is simply not true, as PDF files may exist
with any name whatsoever and still be PDF files, such as in a browser
cache. Use this construct instead using the desired dirname:

find dirname -type f -size +5M | xargs file | grep PDF | cut -d: -f1

It's possible to refine the find command if, for instance, your filenames
may contain spaces.
