Number lines of file and assign variable to each number
I have a file with a list of config files numbered on the lefthand side 1-300. I need to have bash read each lines number and assign it to a variable so it can be chosen by the user called by the script later.

Ex. 1 some data
2 something else
3 more stuff

which number do you want?

then the user would input the number, and that line would be stored as a variable to be gotten later. But I have many lines to this file so I want bash to just grab a variable from each number on the left hand column.
