ln -s soft links knowledge summary
1, soft and even established: ln -s source file of the soft link file
2. Myth: soft link is created, it means that there is a soft link to the file can not be created before
3, analogy: win Shortcuts
4, delete: rm can, but the source file will not be affected
5, failure: no more source files or change the path; ls -l will see when viewing the source file has a flashing red background
6, the difference between: own inode (compared to hard link)
7, point: you can point to files, directories
8, Application: hide the source file path, real name, software upgrades
9, long-winded: hard links can not point to a directory, but you can play that game - a soft link refers to the directory - Create a hard link for the soft link
Example: / home / oldboy (oldboy directory)
ln -s / home / oldboy / tmp / oldmy (hidden source file path name)
ln / tmp / oldmy / oldyou (hard copy links create a soft link)
