Yes, there is a problem using the back-quote, aka `. The contents of the string enclosed in the back-quotes are invoked as a command, and the command's output replaces the back-quoted string. For example:
Code:
file `which ls`

is expanded into:
Code:
file /bin/ls

You need to use single-quotes: '

Look at the bash or ksh manual pages for more information about quoting and command line expansion.

man

MAN(1)							      General Commands Manual							    MAN(1)

NAME

       man, lookman - print or find pages of this manual

SYNOPSIS

       man [ option ...  ] [ section ...  ] title ...

       lookman key ...

DESCRIPTION

       Man  locates  and prints pages of this manual named title in the specified sections.  Title is given in lower case.  Each section is a num-
       ber; pages marked (2S), for example, belong to chapter 2.  If no section is specified, pages in all sections are printed.   Any	name  from
       the NAME section at the top of the page will serve as a title.

       The options are:

       -p     Run proof(1) on the specified man pages.

       -t     Run troff and send its output to standard output.

       -n     (Default) Print the pages on the standard output using nroff.

       Lookman prints the names of all manual sections that contain all of the key words given on the command line.

FILES

       /sys/man/?/*
	      troff source for manual; this page is /sys/man/1/man

       /sys/man/?/INDEX
	      indices searched to find pages corresponding to titles

       /sys/lib/man/secindex
	      command to make an index for a given section

       /sys/lib/man/lookman/index
	      index for lookman

SOURCE

       /rc/bin/man
       /rc/bin/lookman

SEE ALSO

       proof(1)

BUGS

       The manual was intended to be typeset; some detail is sacrificed on text terminals.
       There is no automatic mechanism to keep the indices up to date.
       Except for special cases, it doesn't recognize things that should be run through tbl and/or eqn.
