Find all mail address in a file using regex

I need to read with powershell a lot of files and getting all email address. I tried this solution

$myString -match '\w+@\w+\.\w+'

The problem is that the variable $matches contains only the first match. Am I missing something?

The Select-String approach works well here. However, this regex pattern is simply not suitable and you should review the following similar question: Using Regex in Powershell to grab email

-match returns strings with the content, so it works better with a string-array where it can find a match per line. What you want is a "global" search I believe it's called. In PowerShell you can do that using Select-String with the -AllMatches parameter.

Try the following:

(Select-String -InputObject $myString -Pattern '\w+@\w+\.\w+' -AllMatches).Matches

Example:

$myString = @"
[email protected] hhaksda [email protected]
dsajklg [email protected]
"@

PS > (Select-String -InputObject $myString -Pattern '\w+@\w+\.\w+' -AllMatches).Matches | ft * -AutoSize
