Find all lines with a length greater than N

Question 1

This is my first question here. I am just beginning with Powershell.

Let’s say I have a text file and I want to match only the lines with a length greater than 10 characters. So I made a really simple regex.

$reg = "^\w{0,10}$"

1 2	$reg = "^\w{0,10}$"

And I use the notmatch operator.

$myTextFile | Select-String -NotMatch $reg

1 2	$myTextFile \| Select-String -NotMatch $reg

This is not working. I also tried

$reg = "^[a-zA-Z0-9]{0,10}$"

1 2	$reg = "^[a-zA-Z0-9]{0,10}$"

but this is not working either.

Any clue for me? Thanks a lot!

Question 2

You don’t need a regex match. Just do this:

Get-Content $myTextFile | ?{$_.Length -gt 10}

1 2	Get-Content $myTextFile \| ?{$_.Length -gt 10}

If you want to do it with a regex, the dot matches any character. This will work…

Get-Content $myTextFile | Select-String -NotMatch '^.{0,10}

...but this is simpler:

<pre><code>Get-Content $myTextFile | Select-String '.{11,}'
