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.

NAME
sysstat - sysstat configuration file. DESCRIPTION
This file is read by sa1(8) and sa2(8) shell scripts from the sysstat's set of tools. It consists of a sequence of shell variable assign- ments used to configure sysstat logging. The variables and their meanings are: HISTORY The number of days during which a daily data file or a report should be kept. Data files or reports older than this number of days will be removed by the sa2(8) shell script. COMPRESSAFTER Number of days after which daily data files are to be compressed, either by gzip or bzip2. SADC_OPTIONS Options that should be passed to sadc(8). With these options (see sadc(8) manual page), you can select some additional data which are going to be saved in daily data files. These options are used only when a new data file is created. They will be ignored with an already existing one. FILES
