I have limited knowledge of UNIX and a fixed witdth file of over 4
million records. I need to match a pattern at a specific location in
each record and replace the value. The following is an example of the
awk I would use to find my pattern
=83=DE awk 'substr($0,153,8)=3D=3D"94695577"'
How can I use this to replace the value.
