Problem with searching and then editing a file through shell.
Hi,

I have searched through this forum as there are many similar entries but could'nt get one of them to work, either that or they were just different to what I needed.

Basically I have a file, recordsDatabase. In this file are a few different fields. There is a unique identifier eg 001 which is a variable the user enters into the application.

I then want to search through the file for the unique identifier field and once the right line has been found prompt the user to enter new information which will then write over the old record and save.

The only part of the code I am struggling with is the part to actually open and edit the file.. I know sed is definately the way forward but I can't for the life of me figure out how to do it...

Any help would be greatly appreciated.

Mikey
