in reply to tagging PDFs with keywords and filtering them later

Image::ExifTool is a module for adding keywords and other searchable metadata to PDF files and various other image formats.

You can use the OO interface, or its command line utility exiftool

% # add keywords to a PDF % exiftool -keywords=perl -keywords=snoopy test.pdf % % # read them back % exiftool -keywords test.pdf Keywords : perl, snoopy

[Corion]: Maybe doing a double-fork (daemonizing) can make go that information away, but maybe not
[Corion]: But I think my knowledge of unix/Linux datastructures is several decades out of date, so I don't really know what information it keeps on processes
[oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
[tye]: I just daemonized and getlogin() still knew who I had been.
[tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
[Corion]: tye: That's really interesting, but maybe it is because getlogin() returns the name, or the uid, so if that user has been replaced by another user with the same uid in the meantime, that's no problem to the system...
[davido]: or on ubuntu /var/run/utmp
[Corion]: Otherwise, I would imagine that a user with a process still alive would lock that information in memory.
