- Hard links must be on the same filesystem as the destination, but symbolic links may be on any filesystem. Is this correct or incorrect?Modify rnfile such that it will keep a copy of the old existing file (if available) before the renaming operating. Assume that apple.txt will be renamed as orange.txt. When the command “./rnfile apple.txt orange.txt” is executed, the script will first check whether orange.txt exists under the given path or not. If the file exists then orange.txt will be renamed as orange.txt_old before renaming apple.txt as orange.txt. Make rnfile an executable shell script; try to rename a file to a filename that already exists. Show your shell program and its output to the instructor.Answer the following which is true false Hard links must be located on the same filesystem as the target, while symbolic links do not have to be located on the same filesystem as the target.
