s/^\D*\d+// # 'first few digits'

Even if this interpretation is correct (and I agree with erix that it’s unlikely), there is no warrant in the OP to remove the non-digit prefix. So the regex would need to be: s/^(\D*)\d+/$1/. For example:

23:21 >perl -wE "$f = 'xyz20130101Customer100.imp'; $f =~ s/^(\D*)\d+/
+$1/; say $f;"
xyzCustomer100.imp

23:22 >

Update (2^nd January, 2013):

Thank-you Anonymous Monk for the improvement below using \K: shorter and “much more efficient”, according to perlre. I’ve learned something useful!

Hope that helps,

That's likely not the right interpretation of his use of 'truncate', which suggests outer positions, no? But I guess the OP should be able to 'figure' it out ;-)

I kinda doubt the op knows what truncate means, or that the OP would know how to apply any of the answers :)
