bug#21712: Suspected bug in find -exec '+'

[Richard White]

The find utility supports execution of a nominated command per file found.  The command argument list is terminated with a ';' parameter.

 

The enhanced GNU version specifies an alternative version of the –exec option using a '+' list terminator.  This option is provided to support an xargs-like batched execution of the nominated command resulting in greater efficiency.

 

It seems like find –exec ';' and find –exec '+' do not behave consistently with regard to '{}' argument expansion. 

 

An example:

 

mkdir /tmp/test

cd /tmp/test

touch a b

find . –type f –exec echo Prefix{}Suffix ';'

è Prefix./bSuffix

è Prefix./aSuffix

find . –exec echo Prefix{}Suffix '+'

è ./b ./a

 

Is the latter result correct?  I would have expected the same result as for the ';' version?
