please help with regular expressions

[Frank]

Hello,

I'm not familiar with regular expressions.
I want fo find all directories which contain the years 2000-2012 in its name and have
a " ", "-" or "_" before the date-string, e.g. " 2009", "-2011" or "_2008".
So far I tried

dir /s /a:d *20[0-1][0-9]*

which is working well.
But I have no idea how to exclude the above mentioned three leading characters.
Any help would be appreciated.

I'm not sure which version you are looking for...

First you say

I want fo find all directories which contain the years 2000-2012 in its name and have a " ", "-" or "_" before the date-string

For that, here's what you need.

dir /s /a:d "::.*[ _-]20(0[0-9]|1[0-2]).*"

Then you go on to say

But I have no idea how to exclude the above mentioned three leading characters.

So here's the solution for that.

dir /s /a:d "::.*[^ _-]20(0[0-9]|1[0-2]).*"

Edit: hang on... that's wrong. Those will give you 2000-2019. One sec and I'll rewrite them.
Edit2: Fixed.

John, excuse me - I was not precise enough.
You're right, my 2nd statement brings a litte bit confusion into my 1st statement ;-)
And (if I'm still at my job for the next years) I also want to find the upcoming years.
Thank you.
