Echox 命令 – 主要带颜色输出

查看 python输出颜色（终端控制台）

ls 命令

1、getopt 模块参数解析 ： Python 命令行参数
2、os.getcwd() 获取当前目录
3、os.listdir(path) 返回path路径下文件列表。os.path.isfile、os.path.isdir 文件和目录判断
4、os.getenv 系统环境属性获取
5、colorama库实现颜色输出：python输出颜色（终端控制台）
6、pyinstall打包：Python程序打包为exe执行文件
7、win+R : sysdm.cpl 环境变量path中设置添加程序 ls.exe 路径

# ! /usr/bin/env python
# -*- coding: UTF-8 -*-

import sys
import os
import getopt
import cmdcolor

exts = os.getenv('PATHEXT').lower().split(';')


def isExt(filename):
    if os.path.isfile(filename):
        for ext in exts:
            if filename.lower().rfind(ext) >= 0:
                return True
    return False

findx 命令

1、getopt 模块参数解析 ： Python 命令行参数
2、os.walk(top[, topdown=True[, onerror=None[, followlinks=False]]]) 目录和子目录下的文件
3、fnmatch.filter 支持正则表达式的匹配
4、os.getcwd() 获取当前目录

# ! /usr/bin/env python
# -*- coding: UTF-8 -*-

import sys
import os
import getopt
import fnmatch


def search_file(filename):
    # print("xhbruce search_file: " + str(filename))
    for root, dirs, files in os.walk(os.getcwd()):
        for file in fnmatch.filter(files, filename):
            print(os.path.join(root, file))


def search_file2(filename):
    # print("xhbruce search_file2: " + str(filename))
    for root, dirs, files in os.walk(os.getcwd()):
        if root == os.getcwd():
            for file in fnmatch.filter(files, filename):
                print(os.path.join(root, file))


def main(argv):
    try:
        opts, args = getopt.getopt(argv, "s")
    except getopt.GetoptError:
        print("getopt.GetoptError: argv = " + str(argv))
        sys.exit(2)

    # print("xhbruce : " + str(opts) + str(args))
    for opt, arg in opts:
        if opt in ['-s']:
            search_file(args[0])

    if len(opts) <= 0:
        if len(args) > 0:
            search_file2(args[0])
