How do I remove all .pyc files from a project?
提问by Teifion
I've renamed some files in a fairly large project and want to remove the .pyc files they've left behind. I tried the bash script:
我在一个相当大的项目中重命名了一些文件，并想删除它们留下的 .pyc 文件。我尝试了 bash 脚本：
rm -r *.pyc
But that doesn't recurse through the folders as I thought it would. What am I doing wrong?
但这并没有像我想象的那样在文件夹中递归。我究竟做错了什么？

In current version of debian you have pycleanscript which is in python-minimalpackage.
在当前版本的 debian 中，您有包中的pyclean脚本python-minimal。

Add to your ~/.bashrc:
添加到您的~/.bashrc：
pyclean () {
find . -type f -name "*.py[co]" -delete
find . -type d -name "__pycache__" -delete
}
This removes all .pyc and .pyo files, and __pycache__directories. It's also very fast.
这将删除所有 .pyc 和 .pyo 文件和__pycache__目录。它也非常快。
Usage is simply:
用法很简单：
$ cd /path/to/directory
$ pyclean

If you're using bash >=4.0 (or zsh)
如果您使用 bash >=4.0（或 zsh）
rm **/*.pyc
Note that */*.pycselects all .pycfiles in the immediate first-level subdirectories while **/*.pycrecursively scans the whole directory tree. As an example, foo/bar/qux.pycwill be deleted by rm **/*.pycbut not by */*.pyc.
请注意，*/*.pyc选择.pyc直接一级子目录中的所有文件，同时**/*.pyc递归扫描整个目录树。例如，foo/bar/qux.pyc将被删除，rm **/*.pyc但不会被删除*/*.pyc。

I used to use an alias for that:
我曾经为此使用别名：
$ which pycclean
pycclean is aliased to `find . -name "*.pyc" | xargs -I {} rm -v "{}"'

find . -name '*.pyc' -print0 | xargs -0 rm
The find recursively looks for *.pyc files. The xargs takes that list of names and sends it to rm. The -print0 and the -0 tell the two commands to seperate the filenames with null characters. This allows it to work correctly on file names containing spaces, and even a file name containing a new line.
find 递归地查找 *.pyc 文件。xargs 获取该名称列表并将其发送到 rm。-print0 和 -0 告诉这两个命令用空字符分隔文件名。这允许它在包含空格的文件名，甚至包含新行的文件名上正确工作。
The solution with -exec works, but it spins up a new copy of rm for every file. On a slow system or with a great many files, that'll take too long.
使用 -exec 的解决方案有效，但它会为每个文件启动一个新的 rm 副本。在缓慢的系统或有大量文件的情况下，这将花费太长时间。
You could also add a couple more args:
您还可以添加更多参数：
find . -iname '*.pyc' -print0 | xargs -0 --no-run-if-empty rm
iname adds case insensitivity, like *.PYC . The no-run-if-empty keeps you from getting an error from rm if you have no such files.
iname 添加了不区分大小写的功能，例如 *.PYC 。如果您没有此类文件，则 no-run-if-empty 可防止您从 rm 收到错误消息。

Further, people usually want to remove all *.pyc, *.pyofiles and __pycache__directories recursively in the current directory.
此外，人们通常希望递归删除当前目录中的所有*.pyc,*.pyo文件和__pycache__目录。
Command:
命令：
find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf
