| The command termination ''+'' instead of ''\;'' highly optimizes the exec clause by not running the rm command for each file present on the file system. It is more ubiquitous, being specified by POSIX. ''-delete'' is from FreeBSD from 1996, not added to GNU find until 2004, ''-exec cmd {} +'' is from SysV in 80s, standardised by POSIX in 1992, added to GNU ''find'' in 2005.
