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...
