How do I paste the content of two folders side by side so that output looks like

some_command dir1 dir2

dir1_file1 dir2_file1
dir1_file2 dir2_file2
dir1_file3 dir2_file3
dir1_file4 dir2_file4
paste ls bash

You could use sdiff and view the 2 directories side by side like so:

$ sdiff <(ls -1 dir1) <(ls -1 dir2)

Any differences between the 2 directories will be reflected with a < or > depending on which side of the comparison is missing a specific file/sub-directory.

Example

$ sdiff <(ls -1 dir1) <(ls -1 dir2)
