Question

这可能非常简单，但我只能在shell / bash中完成此操作。我输入了类似“ a/b/c/d的内容，我想用“ /”替换所有的“ \/”，输出将是“ a / b / c / d”

另一个示例是12.12.12.12/32 >>> 12.12.12.12\/32

任何帮助将不胜感激。

Answer 1

您可以使用bash的参数扩展：

$ input="a/b/c/d"
$ echo "${input//\//\\/}"
a\/b\/c\/d

给定变量input，${input//xxx/yyy}产生input的内容，每个xxx被yyy替换。这里的xxx是\/（必须转义/才能不与下一个/混淆），而yyy是\\/（{{ 1}}，其中\/被转义了。

Answer 2

根据您访问要替换的文本或字符串的方式，类似的方法可能会起作用。您必须在sed命令中同时退出/和\。

var='a/b/c/d'
echo "$var" | sed 's/\//\\\//g'

仅使用bash

Answer 4

这可以做到：

echo "12.12.12.12/32" |sed 's,/,\\/,g'

输出：

12.12.12.12\/32

在这种情况下，请使用除/之外的定界符，如上例中我使用的,一样。您可以使用例如：#，? .... etc

在bash / shell脚本中将所有的'/'替换为'\ /'
