Re: xargs prompts with the same string, but executes differently

[積丹尼 Dan Jacobson]

OK, but

    '-I REPLACE-STR'
    '--replace[=REPLACE-STR]'
    '-i[REPLACE-STR]'
         Replace occurrences of REPLACE-STR in the initial arguments with
         names read from standard input.  Also, unquoted blanks do not
         terminate arguments; instead, the input is split at newlines only.
         If REPLACE-STR is omitted (omitting it is allowed only for '-i'),
         it defaults to '{}' (like for 'find -exec').  Implies '-x' and '-l
         1'.  The '-i' option is deprecated in favour of the '-I' option.

still needs to add a tip to use -p or -t to see the quoting realities of
how REPLACE-STR is used...
