Hello, I'm writing a bash script and I have a question.
Here's what I'm doing:
I have a file called inv.dat which contains the following:
The Bash script is named manage.bash and here is what it does:
Prompts the user for the item code number. If the Item Number doesn't exist, generate an appropriate error message and terminate your shell script.
Do not ignore case sensitivity when searching for item code number. If the item number exists, extract the item quantity, prompt the user for the amount of items to increase the value in the database.
Heres what running the script looks like:
Here is the portion of my script that performs the addition:
The addition is performed successfully using this script, however when i use the append command, it of course will add the new value to the bottom of the inv.dat file. Is there any way to add the new value and replace the old one? The point of the script is to update the quantity of the item in the database, does anyone have an ideas on how to do this? Would a Sed command help solve this issue?
Guys, I have a variable in a script that I want to transform to into something else Im hoping you guys can help. It doesn't have to use sed/awk but I figured these would be the simplest.

This sounds easy but as a... (2 Replies)
