Seria melhor usar a -exec action (opção) de find
e citando seus argumentos.
Exemplo:
find . -type f -exec grep stuff '{}' \;
As aspas impedirão que os espaços sejam interpretados e você não precisará canalizar tudo através de xargs desnecessariamente.
Na página find man:
-execcommand;Execute command; true if 0 status is returned. All following arguments to
findare taken to be arguments to the command until an argument consisting of ‘;’ is encountered. The string ‘{}’ is replaced by the current file name being processed everywhere it occurs in the arguments to the command, not just in arguments where it is alone, as in some versions offind. Both of these constructions might need to be escaped (with a ‘\’) or quoted to protect them from expansion by the shell. See the EXAMPLES section for examples of the use of the-execoption. The specified command is run once for each matched file. The command is executed in the starting directory.There are unavoidable security problems surrounding use of the
-execaction; you should use the-execdiroption instead.
