从输出清除颜色 [英] Removing colors from output

问题描述

您好我有一些脚本，产生颜色和我需要摆脱了这一点。

Hi I have some script that produce colors and I need to get rid of this.

#!/bin/bash

exec > >(tee log)   # redirect the output to a file but keep it on stdout
exec 2>&1

./somescript

的输出是（在日志文件中）：

The output is (in log file):

java (pid  12321) is running...@[60G[@[0;32m  OK  @[0;39m]

我不知道怎么把这里的ESC字符，所以我把 @ 在它的地方。

我改剧本为：

#!/bin/bash

exec > >(tee log)   # redirect the output to a file but keep it on stdout
exec 2>&1

./somescript | sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]//g"

但现在它给我（在日志文件中）：

But now it gives me (in log file):

java (pid  12321) is running...@[60G[  OK  ]

我怎么也删除该 @ 60G ？

也许有一种为整个脚本完全禁用着色？

Maybe there is a way to completely disable coloring for the entire script?

推荐答案

根据维基百科，该知道所有的东西， [M | K] 在你使用的是专门用来处理 SED 命令 M （颜色命令）和 K （以下简称擦除行的一部分命令）。您的脚本试图绝对光标位置设置为60（ ^ [[60G ），以获得在一条线上，你的 SED 行不包括。

According to Wikipedia, which knows all things, the [m|K] in the sed command you're using is specifically designed to handle m (the color command) and K (the "erase part of line" command). Your script is trying to set absolute cursor position to 60 (^[[60G) to get all the OKs in a line, which your sed line doesn't cover.

（正确， [M | K] 也许应该是（M | K）或 [mK的] ，因为你没有尝试匹配管道符。但是现在这并不重要。）

(Properly, [m|K] should probably be (m|K) or [mK], because you're not trying to match a pipe character. But that's not important right now.)

如果您切换，为最后一场比赛在命令 [MGK] 或（M | G | K） ，你应该能够赶上那额外的控制序列。

If you switch that final match in your command to [mGK] or (m|G|K), you should be able to catch that extra control sequence.

./somescript | sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[mGK]//g"
