This could truly be a bash function and a text file. I can scratch something up later maybe. Function that loads the lines of the text file into an array, assigns then each a number or symbol, then displays the list, waits for input, runs the corresponding like and quits. Ezpz. The hardest bit would be the array methinks.

which i will do with whatever knowledge remains of the one programming class i took like a decade ago

if that's the only option

Got this far tonight, will have to do more tomorrow, have to work early:

line-launcher () {
XIFS=$IFS 

linefile=$HOME/.config/runthese 

mapfile -t array <$(cat $linefile)

echo -e "line-launcher runs your choice of line from $linefile\nThere is no error checking, the contents of that file are your responsibility.\n\n\tPlease choose from the following:"

selector=1

# trouble with the display here, probably will switch out for a 'for i in 0..${!array[-1]}'
IFS='\n'
for c in ${array[@]}: 
  do
    echo -e "\t\t$selector\t$c"
done
IFS=$XIFS 

# need to read a new selection variable here

# then use it in an eval(${array[$selection]}) line or something here 
}

line-launcher () {
# Stash the value of the IFS variable for later
# restoration.

# This is the file with your pre-built commands.

# Convert the file to an array we can use in the

mapfile -t array < $linefile

here is the contents of my ~/.config/launchlines:

ls -l /
echo foo bar
uname -a
which bash

Which gives me output like this:
