Question command to remove characters from a string

Hi All,

I'd like to create a script that would look into a file and remove characters from it.
For example:

file name: test

the file contains the following data: UPC/retail price

001234123820 $12.00
001245452814 $16.00
001234123373 $44.00
001234565532 $159.00

So I want to remove the first 4 characters of each line, the last character from the UPC code and the retail price including the dollar sign. (This is not a homework assignment, it is a painful process that I do at work but with many many more UPCs)

Thank you!!!

many many ways to do it

the simplest being cut

cut -c 5-11 InputFile
when you re-word your question, you only want characters 5 to 11

Hi Fireat,

I know there are many ways. I kinda looked it up in google today; however, I got a little overwhelmed with the answers.

Would "cut -c 5-11 InputFile" remove the strings from every line in my file? Let's say about 20 or more lines.

and correct! I only want characters 5 to 11.

I will test this tomorrow at work.

Thank you
