可以使用 cp 复制，或 sync 同步，或者 mv 移动
https://docs.aws.amazon.com/cli/latest/reference/s3/cp.html
下载文件 aws s3 cp <S3Uri> <LocalPath>
上传文件 aws s3 cp <LocalPath> <S3Uri>
S3Uri 格式：
s3://bucket-name/object-key-or-prefix
记录或下载 Access Key ID 和 Secret Access Key。
Generate random characters
Math.random().toString(36).replace(/[^a-z]+/g, '').slice(0, 5);
Math.random()，生成随机数，例如：0.09751664076957856
.toString(36)，转换成36进制后的字符串。输出类似：“0.3idqid3cvvy”
.replace(/[^a-z]+/g, '') ，仅保留小写自负。输出类似：“idqidcvvy”
.slice(0, 5), 截取前5个字符。输出类似："idqid"
引用自stackoverflow:
from tkinter import Tk
r = Tk()
r.withdraw()
r.clipboard_clear()
r.clipboard_append('i can has clipboardz?')
r.update() # now it stays on the clipboard after the window is closed
r.destroy()
注意：需要启用 tkinter
列出指定目录下的全部文件，或可以通过扩展名指定文件类型，也可以通过指定排除规则，忽略部分文件。
def list_files(
dir: str, ext: list = None, recursive: bool = True, excludes: list = None
):
"""
Args:
- dir, directory path.
- ext, file extension list, lowercase letters. Default is None, which means all files.
- recursive, Default is True, will list files in subfolders.
- excludes, exclude folder or file name list, regexp pattern string. Default is None, which means all folders
Tips:
- How to get relative path of a file: os.path.relpath(file_path, dir_path)
- How to get only name of a file: os.path.basename(file_path)

目前（Python 3.8）为止，Python 并没有原生支持访问系统剪贴板。
搜寻出有几种方法，梳理如下：
简单有效。但是并不适合复杂环境。
import os
# on macOS
def write_to_clipboard(text):
command = f"echo '{text}' | pbcopy"
os.system(command)
def read_from_clipboard():
command = "pbpaste"
return os.popen(command).read()
更多 Shell 命令参考：Shell use clipboard to copy and paste
Qt/Pyside2 读取系统剪贴板内容
import sys
from PySide2.QtWidgets import QApplication
app = QApplication(sys.argv)
clipboard = app.clipboard()
print(clipboard.mimeData().formats())
print(clipboard.mimeData().data(clipboard.mimeData().formats()[0]))
app.closeAllWindows()
app=None
mimeData() 就和 drag 时对 mimeData() 的操作一样了。
引用自 doc.qt.io:
QClipboard supports the same data types that QDrag does, and uses similar mechanisms. For advanced clipboard usage read Drag and Drop .
