我有一个包含几个以 .pyc 结尾的文件的目录，我想一次性全部删除。我都试过了

find . -name '*pyc' | rm

和

find . -name '*pyc' -exec rm

但是，这些语句都不符合用法(在第一种情况下)或语法正确(在第二种情况下，我得到 find: -exec: no terminating ";" or "+" )。如何将结果“管道”到“删除”命令？

Answer 1

find . -name '*.pyc' -exec rm -- '{}' +

来自 man find :

• -exec utility [argument ...] ; True if the program named utility returns a zero value as its exit status. Optional arguments may be passed to the utility. The expression must be terminated by a semicolon (;). If you invoke find from a shell you may need to quote the semicolon if the shell would otherwise treat it as a control operator. If the string {} appears anywhere in the utility name or the arguments it is replaced by the pathname of the current file. Utility will be executed from the directory from which find was executed. Utility and arguments are not subject to the further expansion of shell patterns and constructs.

• -exec utility [argument ...] {} + Same as -exec, except that {} is replaced with as many pathnames as possible for each invocation of utility. This behaviour is similar to that of > xargs(1).

{}不需要在 bash 中引用，但这有助于与其他一些扩展 shell 兼容。
