Please help me with the following Shell script

the scripts seems to ask for a binary operator ..

# mgrep -- search for a file for 3 words in a line
# usage -- mgrep FILENAME word1 word2 word3.

file=$1

if test grep $2 $file
then
if test grep $2 $file | grep $3
then
if test grep $2 $file | grep $3 | grep $4
then
grep $2 $file | grep $3 | grep $4
else
echo $4 not found.
fi
else
echo $3 not found.
fi
else
echo $2 not found.
fi

Hello,

try this in your if statement:

if test -n "grep $2 $file"
Note: an equivalent syntax:
if [ -n "grep $2 $file" ]
