文本中的特殊字符处理问题

heiheihacker

从存储里通过ssh收的日志源文件有很多特殊字符，影响shell处理，请大家帮忙看看如果处理有特殊字符的日志文件，谢谢。以下是日志源文件，已将部分乱码标为红色，剩下的乱码跟标颜色的类似：
Trying ::1...
Connected to localhost.
Escape character is '^]'.

$ perl -ne '{s/\x1b\[\d*\w//g;print}' FILE

or dump your file

$ hexdump -C FILE

hi，我刚才又将哪些属于乱码的部分标了一下颜色，因为我看了您用perl写的那条语句漏掉了个别的乱码，您在帮忙看看，另外您说的hexdump -C FILE好像不行吧？
