What about just the dir command? Is it not possible for an IFS driver to get something reported as <SYMLINK> or <SYMLINKD> by the cmd.exe dir command? So it sounds like MS added symlink support only to NTFS, rather than doing it in a truly generic way. That stinks.
Thanks for your response. This got me curious how it might work the other way (creating symlinks in afs using windows tools) The Windows mklink command just refuses: Z:\users\j\s\h\jsharper\myafsdir>mklink mymklinklink myrealfile The file or directory is not a reparse point. Interestingly, the Cygwin ln command seems to create something that is understood to be a symlink by Cygwin's ls.exe (but not their find.exe) but in reality appears to actually be a binary file: jsharper@MARVINK /afs/asu.edu/users/j/s/h/jsharper/myafsdir $ ln -s myrealfile mywinsymlink jsharper@MARVINK /afs/asu.edu/users/j/s/h/jsharper/myafsdir $ ls -l total 6 drwxr-xr-x 1 jsharper None 0 Dec 5 12:41 . drwxr-xr-x 1 jsharper None 0 Mar 27 1997 .. -rw-r--r-- 1 jsharper None 3 Dec 5 12:41 myrealfile -rw-r--r-- 1 jsharper None 10 Dec 5 12:41 mysymlink lrwxrwxrwx 1 jsharper None 10 Dec 5 13:09 mywinsymlink -> myrealfile jsharper@MARVINK /afs/asu.edu/users/j/s/h/jsharper/myafsdir $ find . -type l jsharper@MARVINK /afs/asu.edu/users/j/s/h/jsharper/myafsdir $ find . -type f ./myrealfile ./mysymlink ./mywinsymlink [back to Linux land...] [jsharper@mooney 13:14:55 -12- /afs/asu.edu/users/j/s/h/jsharper/myafsdir]% ls -l total 3 -rw-rw-r-- 1 jsharper jsharper 3 Dec 5 12:41 myrealfile lrwxr-xr-x 1 jsharper jsharper 10 Dec 5 12:41 mysymlink -> myrealfile -rw-rw-rw- 1 jsharper jsharper 34 Dec 5 13:09 mywinsymlink [jsharper@mooney 13:14:56 -12- /afs/asu.edu/users/j/s/h/jsharper/myafsdir]% hexdump -C mywinsymlink 00000000 21 3c 73 79 6d 6c 69 6e 6b 3e ff fe 6d 00 79 00 |!<symlink>..m.y.| 00000010 72 00 65 00 61 00 6c 00 66 00 69 00 6c 00 65 00 |r.e.a.l.f.i.l.e.| 00000020 00 00 |..| 00000022 Jason
