由于windows上面没有类似linux上面的grep命令，所以下面的python脚本来代替其能力。
grep.py

import argparse
import reif __name__ == '__main__':arg_parser = argparse.ArgumentParser()arg_parser.add_argument("grep")arg_parser.add_argument("file")arg_parser.add_argument("-o", "--out", help="存储路径", required=False)args = arg_parser.parse_args()logfile = open(args.file, "r")grep = args.greptry:of = open(args.out, mode="w") if args.out else Nonewith open(args.file, mode="r", encoding='utf-8') as f:line = f.readline()while line:if re.search(grep, line):if of:of.write(line)else:print(line, end="")line = f.readline()if of:of.close()except KeyboardInterrupt:pass

对文件内容进行过滤：python3 grep.py 匹配字符 file.log
对文件内容进行过滤并保存到文件：python3 grep.py 匹配字符 file.log -o temp.log
