You can see two differences here. The first is that the `find` output has the full paths to the found files, relative to the current working directory from which `find` was run whereas `ls` only has the filenames. You may have to adjust your code to not add the directory to the filenames as you process them when moving from `ls` to `find`. You can see two differences here.

You may have to adjust your code to not add the directory to the filenames as you process them when moving from `ls` to `find`, or (with GNU find) use `-printf '%P\n'` to print just the filename.
The second difference in the two outputs is that the `find` command includes the searched directory as an entry. This can be eliminated by always using a negative name option for the searched directory: The second difference in the two outputs is that the `find` command includes the searched directory as an entry. This can be eliminated by also using `-mindepth 1` to skip printing the root path, or using a negative name option for the searched directory:
