We do not offer home work solutions here. As a general hint, try reading the man page for your shell. Look for the section on conditional expressions. Also see the man page on "test"
 
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

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. MAN(1)
