Well, it does not work and executes sed and grep.

Should you be "modifying data in file" 'in place', not making a new file you then swap in place of the original? Writing the middle of one existing file is not the usual "shell" task, never mind all fields must be fixed length padded!

(If this is schoolwork, you need to follow the template and right forum rules.)
