i have a text file which contain some text like

we|are|one|only
i|am|learning|c++


the input from stdout will be

input1 we
input2 one

it should search in the file where this two strings are and then give the
output :

output1 are
output2 only

similarly

input1 i
input2 learning

output1 am
output2 c++

based up on the input searched we get the output fileds.| are the delimirters

Please read rules and regulation of the forum.

Your questions seems to be a homework assignment. Try to figure out yourself.

Hi,

This is just a vague sample of the above req mentioned.
not thoroughly tested.

echo "give the first input."
read input1

echo "give the second input."
read input2

line=`grep $input1 <filename> | grep $input2 <filename>`
output1=`echo $line | cut -f1 -d"|"`
if [ $output1 = $input1 ]
then
output1=`echo $line | cut -f2 -d"|"`
fi
output2=`echo $line | cut -f3 -d"|"`
if [ $output2 = $input2 ]
then
output2=`echo $line | cut -f4 -d"|"`
fi

echo "output1: $output1"
echo "output2: $output2"


Please let me know if my understanding and proceeding with the req was correct or not.
