Your question is incomplete, but I think you are looking for select myvideo in ${myvideos[@]} — William Pursell

How are you setting myvideos? My guess is you don't actually have an array. — chepner

Maybe this example can help you shed some light:

[aesteban@localhost ~]$ MyVideos=("INTEL" "NVIDIA" "RANDONONNJSDHF")
[aesteban@localhost ~]$ 
[aesteban@localhost ~]$ for entry in "${MyVideos[@]}"; do echo $entry; done;
INTEL
NVIDIA
RANDONONNJSDHF
[aesteban@localhost ~]$

Good luck!!
