Any difference between "cat file" and "cat<file"?

[Ron Wessels]

[* RAID *]

    There is one significant difference that comes about if the program
in question is setuid.  Depending on the file permissions of the user and
the program owner, one of "prog file" and "prog < file" may fail, while
the other succeeds.  "uux" using a private file is one example that comes
to mind.
