Grep command error
I am using a command but getting an error despite of modifying it many times.
Code:
Pattern=`grep story file|cut -c 19-24`

Where as 'story' is the pattern to be matched and i want to cut the value of characters ranging from 19 to 24 when this pattern is found in a variable.

file consists of below log:

A short story is a brief work of literature
usually written in narrative prose
Emerging from earlier oral telling traditions


Am I doing something wrong. This command is being written in a shell script
