Order-only prerequisites are only checked for existence and not newness to determine if a dependency requires an update. For a more fulfilling explanation, please see: http://www.gnu.org/software/make/manual/html_mono/make.html#SEC29 And here is an example usecase. subdir/somefile: somefile.src | subdir cp somefile.src subdir/somefile subdir: mkdir -p subdir If you modify the contents of the subdirectory `subdir', it won't result in subdir/somefile being rebuilt.
