Shell Programming and Scripting

The text line has the following formats:

what.ever.bla.bla.C01G06.BLA.BLA2
what.ever.bla.bla.C11G33.BLA.BLA2
what.ever.bla.bla.01x03.BLA.BLA2
what.ever.bla.bla.03x05.BLA.BLA2
what.ever.bla.bla.Part01.BLA.BLA2

and other similar ones, I need a way to select the "what.ever.bla.bla" part out of the text.

So basically it has to be based on such regex:

Code:

(.*?)(C[0-9]+G[0-9]+|[0-9]+x[0-9]+|Part[0-9]+)

where (.*?) is the part I want to extract... any ideas?

Sorry, its not clear to me.

Do you want to extract the first or the second part?

what.ever.bla.bla - no need to extract this as its a constant

C01G06.BLA.BLA2 - for this just strip off the above pattern

Code:

sed 's/\(.*\)\(C[0-9][0-9]*G[0-9][0-9]*\)\(.*\)/\1/'

The what.ever.bla.bla was just an example, it does differ.
It can be Example1.C11G33 or Bla123.Bla123.C11G33 and so on,
I need to extract always the name that is befor the "C11G33" no matter what it is .*?

The only thing that stays is the C11G33 or 01x03 or Part01 just with different numbers, just look on my regex example again.

That's perfect, thanks!
