No matter which slash you use, they both resolve to the same file (only the metadata may be different), so the inode is the same. The inodes for "a" and "b" aren't the same, so diff goes ahead and does the comparison (which reports the differences in line endings). Try "ln a c" and compare "a" with "c" using your syntax. :-) Igor -- http://cs.nyu.edu/~pechtcha/ |\ _,,,---,,_ pechtcha@cs.nyu.edu ZZZzz /,`.-'`' -. ;-;;,_ igor@watson.ibm.com |,4- ) )-,_. ,\ ( `'-' Igor Pechtchanski, Ph.D. '---''(_/--' `-'\_) fL a.k.a JaguaR-R-R-r-r-r-.-.-.
