In DOS you use `dir` to list files in a directory. You can also use `dir` to list files that match a string in a directory. `dir 1.png` would list all PNGs with a "1" in their name. You need a separate command with options and a flag to do that in bash. In DOS, it's less than a dozen characters, and it's far more intuitive than having to use `find`. Sure, `find` and `ls` might be more flexible, but definitely not more intuitive.
