在 Linux (bash) 中使用 SED 在匹配前后突出顯示匹配的模式和更多字符

Question

我在一個文件中有兩組數據列，如下所示：

我想要的是：突出顯示（使用 SED）匹配 0/1 的“整個條目”。

我已經使用 SED 實現了以下目標：

我想要實現的是：

如何突出顯示 0/1 前后的 31 個字符
（0/1 包含在突出顯示中，如第二張圖片中所示）

我使用以下代碼突出顯示 0/1：

cat /home/McFly/myPods.log | sed -ue 's/\(0\/1\)/'`printf '\033[1;31m'`'\1'`printf '\033[0m'`'/g'

我知道這可以使用 GREP 來實現。
我需要使用 SED 來實現它。

輸出仍然存在一個小問題 | watch -n 1 --color ./myScript.sh給出：

Answer 1

假設這兩個塊在同一行，並且你想為背景而不是文本添加顏色，你可以試試這個sed

$ sed -E s"~[a-z]+-[^/]*0/1([^0-9]*.){2}[^ ]*~$(tput setab 1)&$(tput sgr 0)~g" /home/McFly/myPods.log

相反，如果您打算像當前代碼那樣為文本而不是背景添加顏色，則將setab 1更改為setaf 1即

$ sed -E s"~[a-z]+-[^/]*0/1([^0-9]*.){2}[^ ]*~$(tput setaf 1)&$(tput sgr 0)~g" /home/McFly/myPods.log
