Greetings, I just came over from LQO where I can't even log-in anymore
In an effort to build a guitar chords quiz I'm trying to code a bash script that
1- builds an array of one directory's contents
(about 300 guitar chord notation images images [prompts])
2- selects a random image from the array
3- screens it
4- sleeps X seconds
5- replaces image by one of same name from another directory
(the same about 300 guitar chord but this time notation + chordbox images)
6- loops Y times a cue/validation .mp3 sharing the name root from yet another directory
7- removes element from array
8- returns to 2 to select another random file from remainder of array
Latest edit of the rudimentary beginnings:
Because my bash in no flash in the pan I need to keep it extremely formatted and tutorial/verbose
All help appreciated, the above WORKS but is embare-assingly rudimentary

#echo "${array[@]}" # will dump all elements of the array
size=${#array[@]} # assign size of array to variable 'size'
rfromsize=$(($RANDOM % size)) # # Pick an array element, rfromsize WAS 'index'before
echo $rfromsize $size > ~/r1-size1.txt
longelement=${array[$rfromsize]}
element=${longelement::-4} # remove (.png) extension extension from longelement to make element
