I am trying to move a data directory to another hard drive (on esata) and ran into a problem I've never run into before - I'm not sure it has anything to do with esata or not... I moved (linked) the software "run" directory on the esata drive into my data directory, but when I tried to reference higher directories in the tree with ../ - it goes higher in the esata's tree rather than higher in the main directories' tree. These software suites sometimes use ../../ referencing to navigate a tree. Maybe that's bad practice? Notice below that entering the link (at least in csh) changes the directory tree. I don't think this is true of linked files. So if I try to run the software from the "test" directory below, it fails - for instance, I can't source my EMS.cshrc file - the "cd .." command remembers where I am (embedded in a linked dir), but the "source" command does not.
