- Subject: What to do about extraneous arguments?
-
- Another aspect of command arguments is: after all the necessary arguments
- have been processed, what if some are left?
-
- Some commands process the whole list, and are intended to do so (e.g.
- ls(1)). Others (e.g. diff(1), cmp(1)) only work on a specific number
- of arguments.
-
- Common practice seems to be to ignore extraneous arguments. A user here
- has requested that cmp(1) be modified to generate a diagnostic if more
- than 2 filenames are provided. This might be helpful when using wildcards
- for filenames, as in:
-
- cmp foo* fum*
-
- If there is more than one file matching 'foo*' and you don't realize it,
- the results are not what you expect. Comments?
