  • find can call grep without xargs invocation, see -execdir, but in this case, the called program grep can iterate itself. Commented Mar 26, 2011 at 12:06
  • xargs will be more efficient, as it will call grep with several filenames at once, instead of one at a time using -exec Commented Mar 26, 2011 at 23:25
  • gnu find can handle mutliple filenames at once too: find . -name "$1" -exec grep --color $2 -- {} + if ended with + instead of ";" Commented Mar 27, 2011 at 19:59
