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.

Change your working directory to your login directory Create the file called share using cat command under your login directory. Enter one or two lines of text in it. Display the content of the share file Display the number of hard links to the share file ONLY using the long option Using echo command, answer how many hard links (hard link count) the share file has. Display the inode number for the share file using appropriate option. Create the subdirectory, linkdir under your login directory Change working directory to Stay in this directory until the rest of this question. Create a hard link called share2 to the share Remember that the share file is the parent directory and NOT in the current working directory. Hence, you need to specify correct relative or absolute pathname for share file in your hard link command.…
Create File comparators that arrange files in ascending/descending order of file size, ascending/descending order of file name, and ascending/descending order of last modification date. Employ these comparators in LS, a programme that accepts a command-line input and lists the files in the current directory in a certain order, such as "-t" to sort by timestamp.To break ties, support several flags. Be certain you use a reliable sort.
