Hi,

I've a textfile with a lots of numbers. After some numbers are comments.
I want delete these comments with sed, but dont know the correct pattern.

for example (my textfile):

PHP Code:


			
3202 mycomment

292-is way to low

1#correct

3  #my whitespace comment

4229 // comment

20.201 // numbers with dots are also in my file

202.02 miaumiau

1.234.99 ''''''FOO

So I want to delete ALL stuff after ne last number ...

correct ouput:

PHP Code:

zaxxon · #2 (**permalink**) 10-22-2008

Code:

sed 's/\(^[\.0-9]*\)[^.0-9]*/\1/g' infile
