RE: [LUG] Something Neil Williams said



Just to add a couple of things, a symbolic link is different from a hard
link.  A hard link (ommit the -s from the ln command) is exactly what a
directory contains, it links a file name to an inode (which contains goodies
like permissions, owner, file type, size, etc.).  It is no coincidence that
the C and Perl call to delete a file is 'unlink'.  Hard links cannot span
partitions, because inode numbers are unique only to partitions.  Symbolic
(or Soft) links can span partitions, and can even refer to files that are
not mounted (such as NFS devices or Samba shares).  The inode of a symbolic
link "points" to a small file containing just the target file name.  Do an
ls -l on the link and you will notice the file size is the same as the
number of characters in the link name.  Modern file systems like ext2 store
the target name in the inode itself if it is relatively small.

Subject: [LUG] Something Neil Williams said


Last night I was having problems with my save as box and was told to

$ ln -s /windows/E ./data

 Neil said (after I called it a shortcut)
"It's much more than a shortcut".
What else can you do with it,and what is it if it isn't a shortcut.A link?
