Thanks Perderabo!

i tried your code and it works great. although i had an error
when i entered the string df/DF.

apalex>cat infile
pattern1 $Major
pattern2 -Crit
pattern3 df/DF
pattern4 h'405
pattern5 \ffe
pattern6 ab >
pattern7 abc >>
pattern8 A"a"
pattern9 `0de`

apalex> cat whereis
#! /usr/bin/ksh
IFS=""
print -n "enter search string -"
read string
sed -n '/'"${string}"'/=' < infile
exit 0

apalex> whereis
enter search string -df/DF
sed: command garbled: /df/DF/=
apalex>

I just thought its easier to type the string on the
command line, so i tried to insert your code in
my script but it really gives me a lot of errors...

apalex> cat whereis1
#!/bin/ksh
case $# in
0) echo "\n\t No pattern(s) entered! Try again."
echo "\t Usage: whereis1 pattern1 [pattern2]"
exit 1 ;;
*) sed -n '/'"${*}"'/=' < infile
exit 0 ;;
esac

it doesn't work on patterns:
$Major, ab > and abc >>

I really appreciate this forum, gives me a chance to improve my
skills. Thanks a lot guys!!!

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
