I want to replace / with // except /N So I got so far

sed ‘s/\\/\\\\/g’

But I’m not sure how to add ignore

CodePudding user response：

You can try

echo '\ \n \\n' |
sed -E 's/\\(n)|(\\)/\\\1\2/g'

\\ \n \\\n

CodePudding user response：

You could try this 's/\/\([^N]\)/\/\/\1/'

Simple match / and the character after, requiring to not match N character.

The matched character (other from N) will be stroed in captureing group and can be used in replacement with \1 :)
