使用python实现unix2dos和dos2unix命令的例子
由于工作电脑网络限制无法安装unix2dos和dos2unix命令转换文件,自己实现一个
直接上代码,保存为python文件如unix2dos.py然后使用命令
unix2dos.py {unix2dos|dos2unix} {dirname|filename}
#! /usr/bin/env python # coding=utf-8 import os import sys try: input = raw_input except: pass def usage(): print('Usage:') print('\t %s' % ('unix2dos.py {unix2dos|dos2unix} {dirname|filename}')) def err_exit(msg): if msg: print('%s' % msg) usage() sys.exit(0) def getfiles(root): for dirpath, dirnames, filenames in os.walk(root): for filename in filenames: yield os.path.join(dirpath, filename) def format_file(file, toformat='unix2dos'): print('Formatting %s:\t%s' % (toformat, file)) if not os.path.isfile(file): print('ERROR: %s invalid normal file' % file) return if toformat == 'unix2dos': line_sep = '\r\n' else: line_sep = '\n' with open(file, 'r') as fd: tmpfile = open(file+toformat, 'w+b') for line in fd: line = line.replace('\r', '') line = line.replace('\n', '') tmpfile.write(line+line_sep) tmpfile.close() os.rename(file+toformat, file) def uni_format_proc(filename, toformat): if not toformat or toformat not in ['unix2dos', 'dos2unix']: err_exit('ERROR: %s: Invalid format param' % (toformat)) if not filename or not os.path.exists(filename): err_exit('ERROR: %s: No such file or directory' % (filename)) if os.path.isfile(filename): format_file(filename, toformat) return if os.path.isdir(filename): for file in getfiles(filename): uni_format_proc(file, toformat) if __name__ == '__main__': if len(sys.argv) != 3: err_exit('ERROR: Invalid arguments') uni_format_proc(filename=sys.argv[2], toformat=sys.argv[1])
以上这篇使用python实现unix2dos和dos2unix命令的例子就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持我们。
