Bash 从输出中删除颜色
我有一些脚本可以生成带有颜色的输出，我需要删除ANSI代码Bash 从输出中删除颜色,bash,unix,colors,console,ansi-escape,Bash,Unix,Colors,Console,Ansi Escape,我有一些脚本可以生成带有颜色的输出，我需要删除ANSI代码 #!/bin/bash exec > >(tee log) # redirect the output to a file but keep it on stdout exec 2>&1 ./somescript 输出为（在日志文件中）： 我不知道如何将ESC字符放在这里，所以我将@放在它的位置 我将脚本更改为： #!/bin/bash exec > >(tee log) # red
#!/bin/bash
exec > >(tee log) # redirect the output to a file but keep it on stdout
exec 2>&1
./somescript
@#!/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"
@[60Gsed[m|K]mK^[[60Gsed[m|K]（m|K）[mK][mGK]（m | G | K）./somescript | sed -r "s/\x1B\[([0-9]{1,3}(;[0-9]{1,2})?)?[mGK]//g"
嗯，不确定这是否适用于您，但'tr'将'strip'（删除）控制代码-尝试：
./somescript | tr -d '[:cntrl:]'
下面的正则表达式将丢失一些序列，以及3位颜色。和在regex101.com上 改用这个：
./somescript | sed -r 's/\x1B\[(;?[0-9]{1,3})+[mGK]//g'
我也有一个问题，有时，SI字符出现 例如，它发生在以下输入中：
echo“$（tput setaf 1）foo$（tput sgr0）bar”@杰夫·鲍曼的解决方案帮助我摆脱了一些色码。 我在正则表达式中添加了另一小部分，以便删除更多：
sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[mGK]//g" # Original. Removed Red ([31;40m[1m[error][0m)
sed -r "s/\x1B\[([0-9];)?([0-9]{1,2}(;[0-9]{1,2})?)?[mGK]//g" # With an addition, removed yellow and green ([1;33;40m[1m[warning][0m and [1;32;40m[1m[ok][0m)
^^^^^^^^^
remove Yellow and Green (and maybe more colors)
./somescript | cat
我无法从其他任何一个答案中得到令人满意的结果，但以下几点对我很有用：
somescript | sed -r "s/[[:cntrl:]]\[[0-9]{1,3}m//g"
如果我只删除了控制字符“^[”，它会留下其余的颜色数据，例如“33m”。包括颜色代码和“m”就完成了这项任务。我对s/\x1B//g不起作用感到困惑，因为\x1B[31m肯定与echo一起工作。这里有一个纯Bash解决方案 另存为
