I agree that nl is better for line numbering, but have you really never used cat with arguments? One of the most common use cases is for concatenating files:

    cat file1 file2 > combined-file

There file1 and file2 are arguments. What do you use cat for?

I mean flag arguments.

sed {} file1 file2 > combined-file
