find: Fehlendes Argument für "-exec" bei Verwendung der Suchform +

Ich möchte einen Befehl auf den Pfaden ausführen, die mit dem findBefehl gefunden wurden, und ich möchte +die Anzahl der Starts des externen Befehls reduzieren.

Kritisch hat der Befehl ein endgültiges Argument mit festem Wert. Hier ist ein konkretes Beispiel mit echoals Befehl, obwohl in der Realität:

mkdir blah && cd blah touch fooA touch fooB find . -name 'foo*' -exec echo {} second + 

Ich würde erwarten, dass dies gedruckt wird:

./fooA ./fooB second 

Stattdessen bekomme ich die Fehlermeldung find: missing argument to-exec ' . I've tried all sorts of permutations to get it to work with +. Why isn't this working? It works find with the\; `variant:

find . -name 'foo*' -exec echo {} second \; ./fooB second ./fooA second 

... aber das ist nicht das, was ich suche.

Hier ist ein Auszug aus den Manpages zu den +und ;Formularen:

 -exec command ; Execute command; true if 0 status is returned. All following arguments to find are taken to be arguments to the command until an argument consisting of `;' is encoun‐ tered. 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 of find. 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 -exec option. The specified command is run once for each matched file. The command is executed in the starting direc‐ tory. There are unavoidable security problems surrounding use of the -exec action; you should use the -execdir option instead.  -exec command {} + This variant of the -exec action runs the specified command on the selected files, but the command line is built by appending each selected file name at the end; the total number of invocations of the command will be much less than the number of matched files. The command line is built in much the same way that xargs builds its com‐ mand lines. Only one instance of `{}' is allowed within the command. The command is executed in the starting directory.
