Finding YYYYMMDD_YYYYMMDD files with regexp

[Uwe Ziegenhagen]

Hi,

I have several hundred files here which accidently got renamed after the
following pattern:

YYYYMMDD_YYYYMMDD-something

where the first date does not match the second date. How can I get the
file which follow this pattern?

Thanks from Germany,

Uwe

This doesn't do an sanity checking on whether the dates make sense, but
it will match your pattern

ls | % {if ($_.name -match "\d{8}_\d{8}-.+") {$_}}

You can change that last {$_} to {$_.name} if you just want this to
print out the file names.
