为什么我们在linux终端中使用这种奇怪的构造from selenium import webdriver def main(): driver = webdriver.Chrome() driver.get("https://login.fmls.com/SAML/login.aspx?ReturnUrl=%2fsaml%2fSAML%2fSSOService.aspx%3fSAMLRequest%3djZLNTsMwEIRfJfKBWxLHrWhrmqCKCilSEagBDlyQ62waS7EdvE7VxydJy98BxMXyrnY934y8RKGblq86X5stvHWAPsjXKXlNaLUDyapwBxULp7tJFQo6KcOFhHkypwDsckaCZ3CorEkJiygJcsQOcoNeGN%252B3aLII6TRk88ck4RPK2Sxi08ULCda9ijLCj5u19y3yOG7sXpmo0g1G0up44IqL1d0mLor7AtxBSYgEtkcS3FonYSROSSUahEH5QSCqA3x2VojgBoUba7DT4M5v5KaEY0ro7xNP280XlRbeqeOIVUb9ca4HwtP1zD2QXbc9g6%252Bd7fZ1yi6Ebq%252BMdVAqB9KnCQmOujHIx8RT0jnDrUCF3AgNyL3kg13eJ8lbZ72VtiHZcpjmY7Du2%252F7f6%252BLDGcn%252B7WMZf1PKTtXPf5G9Aw%253D%253D%26RelayState%3dMatrix%2bSAML%2bLogin") form = driver.find_element_by_xpath("//form") print(form.get_attribute('innerHTML')) driver.quit() if __name__== "__main__": main()作为exec命令？例如，

Answer 1

来自man page of find（重点是我）：

find . -type f -exec file '{}' \;
在当前目录中或当前目录下的每个文件上运行`file'。注意，括号用单引号引起来，以防止将其解释为shell脚本标点符号。 分号也受到反斜杠的保护，尽管在这种情况下也可以使用单引号。

Answer 2

寻找信息时，我在AskUbuntu中找到了这篇帖子，我认为这是StackOverflow的一个家庭，其中用户询问与您的要求相同。
