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!!!

locate

LOCATE(1)						    BSD General Commands Manual 						 LOCATE(1)

NAME

     locate -- find files

SYNOPSIS

     locate [-d dbpath] pattern

DESCRIPTION

     locate searches a database for all pathnames which match the specified pattern.  The database is recomputed periodically, and contains the
     pathnames of all files which are publicly accessible.

     Shell globbing and quoting characters (``*'', ``?'', ``'', ``['' and ``]'') may be used in pattern, although they will have to be escaped
     from the shell.  Preceding any character with a backslash (``'') eliminates any special meaning which it may have.  The matching differs in
     that no characters must be matched explicitly, including slashes (``/'').

     As a special case, a pattern containing no globbing characters (``foo'') is matched as though it were ``*foo*''.

     Options:

     -d dbpath
	   Sets the list of databases to search to dbpath which can name one or more database files separated by ``:'', an empty component in the
	   list represents the default database.  The environment variable LOCATE_PATH has the same effect.

EXIT STATUS

     locate exits with a 0 if a match is found, and >0 if no match is found or if another problem (such as a missing or corrupted database file)
     is encountered.

FILES

     /var/db/locate.database	   Default database
     /usr/libexec/locate.updatedb  Script to update database.

HISTORY
