Probably the easiest trick to do is to create aliases of every .sty and .cls file (located in your 'style files' directory) and put them wherever you need them. This is not (only) for saving space, but for unity.

where to put .sty and .cls file for project
When I try to find the current working directory at a linux command prompt (using "pwd"), it will show the directory with symbolic links included. For example, if I make a symbolic link and use it to visit that directory:

ln -s /mnt/backup /home/biotech/backup
cd /home/biotech/backup
pwd


This will show "/home/biotech/backup" instead of "/mnt/backup". This happens on both Ubuntu and Cygwin.

What command can I use to see the latter, the "real" directory?
