I have a bash script that runs and outputs to a text file however the colour codes it uses are also included what i'd like to know is how to remove them from the file, ie
我有一个运行并输出到文本文件的 bash 脚本，但是它使用的颜色代码也包括在内，我想知道如何从文件中删除它们，即
^[[38;1;32mHello^[[39m
^[[38;1;31mUser^[[39m
so I just want to be left with Hello and User
所以我只想留下你好和用户

sed -r "s/\x1B\[(([0-9]{1,2})?(;)?([0-9]{1,2})?)?[m,K,H,f,J]//g" file_name
this command removes the special characters and color codes from the file
此命令从文件中删除特殊字符和颜色代码
these are some of ANSI codes:
ESC[#;#H or ESC[#;#fmoves cursor to line #, column #
ESC[2Jclear screen and home cursor
ESC[Kclear to end of line,
这些是一些 ANSI 代码：
ESC[#;#H or ESC[#;#f将光标移动到第 # 行，第 # 列
ESC[2J清除屏幕和主页光标
ESC[K清除到行尾，
note in case of clear code there is neither number nor semicolon ;
请注意，如果代码清晰，则既没有数字也没有分号 ;
agree with below comment: if the numbers are more than 2 digit kindly use this:
同意以下评论：如果数字超过 2 位，请使用：
sed -r "s/\x1B\[(([0-9]+)(;[0-9]+)*)?[m,K,H,f,J]//g" filename

My solution:
我的解决方案：
... | sed $'s/\e\[[0-9;:]*[a-zA-Z]//g'
The colon is there to support escapes for some old terminal types.
冒号用于支持某些旧终端类型的转义。
