Why doesn't find work with xargs?

Question

linux

Hello.
There is a project build script in Jenkins, the following command is called there:

call(['find', '/path/to/site', '-type', 'd', '-exec', 'chmod', '755', '{}', ';'])

Everything would be fine if it weren't so slow. Found another solution:

call(['find', '/path/to/site', '-type', 'd', '|', 'xargs', 'chmod', '755'])

But it throws an error:

find: paths must precede expression: |
Usage: find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]

What is the problem?

Answer 1

maybe because | no one to process? in the first case you call one command, in the second you call two commands through the pipeline...
