推荐答案
您需要转义双引号,并且由于您的正则表达式使用空格,因此请使用 / c
切换以传递搜索字符串而不是用空格分隔的正则表达式:
you need to escape the double quote, and since your regular expression uses spaces, use the /c
switch to pass a search string instead of space separated regexes:
findstr /I /c:"port\" : " *
来自此处:
多个正则表达式ns可以用空格分隔,只是
与分隔多个单词相同(假设您未使用/ C指定
文字搜索),但是如果正则表达式
本身包含,则此方法可能无用空格。
multiple Regular Expressions can be separated with spaces, just the same as separating multiple words (assuming you have not specified a literal search with /C) but this might not be useful if the regex itself contains spaces.
