How to print this using sed?
Hi

Imagine that I have a text file containing the following student's data:

student: john
group: A
sex: male
age: 25

student: alice
sex: female
age: 20
group: B

It is guarantee the details will start by "student:", and then followed by the sex, age and group in any order.

Is it possible to print the age of alice using the sed?

sed eh?
Try this:
Code:
s=alice; sed -n "/student: $s/,/^age:/{s/^age:/$s:/p;}" infile

No homework questions in the main forums. There's a special sub forum set aside for that.
