exist?
@Rudic sorry that was by overlook. With parameter 3 the row returned should be the third row ie.
Code:
-rwxrwxrwx 1 user1 user 21624 Feb 11 17:13 httpd.conf_1581421456

Likewise when the user passes 4 the 4th latest row should be returned i.e
Code:
-rwxrwxrwx 1 user1 user 15445 Feb 11 15:39 httpd-ssl.conf_1581421372

But, as I shared the output of your suggestion i get a list of rows and not that single particular row corresponding to the argument passed to the script.

@vbe thank you for the points you highlighted however, the parameter is checked by a Jenkins UI tool and my script will only be executed once a number is passed to that script by the user. Thus the argument to my script is certainly an integer.

Kindly suggest

rcp(1c) 																   rcp(1c)

Name
       rcp - remote file copy

Syntax
       rcp [ -p ] file1 file2
       rcp [-r] [-p] file... directory

Description
       The command copies files between machines.  Each file or directory argument is either a remote file name of the form rhost:path, or a local
       file name.  Local file names do not contain colons (:) or backslashes () before colons.

       Note that the command refuses to copy a file onto itself.

       If path is not a full path name, it is interpreted relative to your login directory on rhost.  To ensure that the metacharacters are inter-
       preted  remotely,  a  remote  host's  path  can be quoted by either using a backslash () before a single character, or enclosing character
       strings in double (") or single (') quotes.

       The command does not prompt for passwords; your current local user name must exist on rhost and allow remote command execution via

       The command handles third party copies, where neither source nor target files are on the current machine.  Hostnames may also take the form
       rname@rhost  to	use rname rather than the current user name on the remote host.  The following example shows how to copy the file foo from
       user1@mach1 to user2@mach2:
	$ rcp user1@mach1:foo  user2@mach2:foo
       Note that the file .rhosts on mach2 in user2's account must include an entry for mach1 user1.  Also note that it may be necessary  for  the
       person implementing the command to be listed in the .rhosts file for mach1 user1.

       By  default,  the mode and owner of file2 are preserved if file2 already exists.  Otherwise, the mode of the source file modified by on the
       destination host is used.

Options
       -p   Preserves the modification times and modes of the source files in its copies, ignoring the

       -r   Copies files in all subdirectories recursively, if the file to be copied is a directory.  In this  case  the  destination  must  be  a
	    directory.

Restrictions
       The  command  is  confused by output generated by commands in a .cshrc file on the remote host.	In particular, `where are you?' and `stty:
       Can't assign requested address' are messages which can result if output is generated by the startup file.
