I use symbolic links quite often, but after moving the original file, I lose track of the symbolic link. I also use symbolic links for keeping track of some files in the same directory, but again, I lose track.  Is there any way (tool/method) to keep track of the symbolic link no matter what change I make? Is the hard link the only way for this?Is there any way to make the symbolic link in a relative way so that when I move the directory that contains both the original and link, the link should work.
Keep tracking of symbolic links?
symlink;hard link
Concering your second question, if you make the symlink using a relative path and then move the whole directory structure, it still should work. Consider the following terminal session:~$ mkdir test~$ cd test/~/test$ mkdir test2~/test$ cd test2/~/test/test2$ touch testfile; echo hello, world > testfile~/test/test2$ cat testfile hello, world~/test/test2$ cd ..~/test$ ln -s ./test2/testfile testfileln~/test$ ls -ltotal 8drwxr-xr-x 2 xxxx xxxx 4096 2010-09-09 09:18 test2lrwxrwxrwx 1 xxxx xxxx   16 2010-09-09 09:18 testfileln -> ./test2/testfile~/test$ cd ..~$ mv test/ testfoo~$ cd testfoo/~/testfoo$ ls -ltotal 8drwxr-xr-x 2 xxxx xxxx 4096 2010-09-09 09:18 test2lrwxrwxrwx 1 xxxx xxxx   16 2010-09-09 09:18 testfileln -> ./test2/testfile/testfoo$ cat testfileln hello, worldAs for your first question, if you really want a link that will refer to the same file no matter what you do with the original location of the file, a hard link is probably what you want.  A hard link is basically just another name refering to the same inode.  Thus, there is no difference between the hard link and the original file.  However, if you need to link across file systems, hard links often do not work and you usually cannot make hard links to directories.  Further, you will notice some differences when performing some file operations.  Most notably, removing the original will not remove the file.  The hard link will still point to the file and be accessible.
