Say we are using ubuntu's bash and we cd to the folder myFolder.

Now, say we use ls in this folder, and we get a list of files:

file1 file2 file3

We want to, for the sake of this example, run file2 on node.

Is there a way to choose the file based on it's position on the ls list/ folder? For example, something like node "secondFileOfFolderHere"?

node "$(ls -1 | awk 'NR==2')"

-1 switch lists one file per line; awk prints line 2
