COM-Interface for accessing file information (title, subject, author)?
Hi, On NTFS, any file can have extended file information based on an Alternate Data Stream. Explorer displays this as a tab in the file properties dialog.

How do I capture the output of a command to a file descriptor in Bourne shell?

I'd prefer to find something that does the moral equivalent of the Unix C function popen, to get a new...

I want to get a list of folders at the current level (not including their subfolders) and simply print the folder name and a count of the number of files in the folder (preferably filtering to *.jpg if possible).

Default encoding for python for stderr?
I've got a noisy python script that I want to silence by directing its stderr output to /dev/null (using bash BTW). Like so: python -u parse.py 1> /tmp/output3.txt 2> /dev/null but it quickly exits prematurely. Hmm. I can't see the traceback because of course that goes out with stderr. It runs noisily and normally if I don't direct ...
