Regex find a word with lookbehind

1

Hi,

I’m learning regex code, i did this to integrate it with a project.

(?<=:)[password]$

login as: sba
srv@ip’s password:

it starts from the end, but can’t find the word password.

Thanks

Try using round parenthesis. Because as it is this will match one single letter of those inside it

Lookbehinds are currently supported only in chrome, so check that.
Now, what are you exactly trying to achieve?

Hi @vytautas-pilk

I’m trying to learn regex and work on my project…

The thing i need to find the word password, if it matches i get to type a text otherwise i don’t…

Then your regex is /password/. Or, with a positive lookahead to check for a colon: /password(?=:)/. It finds the word ‘password’ in your string. Not sure why would you need a positive lookbehind, may you elaborate, please?

Thank you @vytautas-pilk

Can you please explain to me why did you took off “<”.

I did follow an example on the forum, and unterstand how they check for the words etc, and following a course, to learn more about regex. I ll need it a lot.

Your welcome. You used positive lookbehind, and I used positive lookahead, that’s why I omitted ‘<’ character. You need positive lookbehinds when you want to match a string/pattern when it’s preceded by something else, and the opposite for positive lookaheads when it is preceding something else.
