在文本文件中添加特殊字符后的空格

Question

我需要帮助分隔文件中的多个if语句。

变化：

 [[ "$File1" == "Word1" ]] || [[ "$File1" == "Word2" ]] ||

为：

 [[ "$File1" == "Word1" ]] ||
 [[ "$File1" == "Word2" ]] ||

我在网上找到的所有内容都不适用于像||这样的特殊字符 我想我需要使用awk或sed，但我不确定如何让它工作。

Answer 1

$ sed 's@|| @||\n@g' input
[[ "$File1" == "Word1" ]] ||
[[ "$File1" == "Word2" ]] ||

Answer 2

您也可以使用awk

awk '{sub(/\|\| /,"&"RS)}1' file

echo "[[ "$File1" == "Word1" ]] || [[ "$File1" == "Word2" ]] ||" | awk '{sub(/\|\| /,"&"RS)}1'
[[  == Word1 ]] ||
[[  == Word2 ]] ||
