Under what circumstances would you use a symbolic link instead of a hard link?
What will be an ideal response?
You must use a symbolic link to link files that are on different devices (an inode cannot point to
disk blocks on a different device). If the files are on the same device, you still might want to use a
symbolic link rather than a hard link in some cases. A symbolic link can exist even if the file it
points to does not. A symbolic link file might be used as a placeholder for a file when the actual
data file doesn’t exist (in which case, a hard link would cause the data to still exist on the disk).
