I've always used complex numbers as a mnemonic: real + imaginary, a + bi (obviously the file is real and the softlink is "imaginary").

The real/imaginary concept is exactly what I use too. I sort of recall being able to use the real/imaginary concept with other Unix commands as well, but I can't recall which ones off the top of my head.


rm only has the real component before you issue it and the imaginary one afterwards ;)
