As we dont know what OS you are using we cant figure out like that what error message you would be getting... but you were asked to try on command line tail -2 <a directory name> to see the behaviour of that command with a directory, we are not going to to your work for you...
Once you have tested and told us the result can we help you go further...
Since if you have corrected now your script to use $2 (which we hope is a numeric value...), you are left with solving how to input files for the given directory...

Hi All,
How can the head command be used to extract only a particular line.
By default head -n filename displays the first n lines. I want only the nth line.
I couldn't get it from forum search.
Thanks,

mkcover
MKCOVER(8) System Manager's Manual MKCOVER(8)
NAME
mkcover - HylaFAX continuation cover page generation command
SYNOPSIS
/var/spool/hylafax/bin/mkcover qfile template result
DESCRIPTION
bin/mkcover is the command invoked by the facsimile server when a continuation cover page is required for an outbound job that is about to
be retried. It generates a single POSTSCRIPT(R) page that is imaged according to the remote capabilities and transmitted as the cover
page. The arguments are:
qfile the job description file for the outbound job.
template the cover page template file, as used by the faxcover(1) program.
result the filename where the resultant POSTSCRIPT document should be written.
The default mkcover command is a shell script that uses awk(1) to parse the job description file and generate the cover page document. The
template file may be optionally compressed with compress(1), pack(1), or gzip(1); the filename suffix is used to decide whether or not the
template file contains compressed data.
