Delete whitespace

Hi,

I have been trying to remove whitespace from a file using sed. Here is an example of what im trying to do:

www1 = www1
www2 = www2
www3 = www3
and all the way to 300 and i want it to look like:

www1=www1
www2-www2
www3=www3
again upto 300

Any help regarding this would be greatfully appreciated
Thanks in advance Smilie

i new at this so hav been tryin everythin i can find by googling the problem

#sed 's/ //g' oldfile > newfile

#sed '$s/ \+//g' oldfile > newfile

and quite a few others similar to this.
one thing that did seem strange is if i do the first one i mentioned it will do the top line i.e www1=www1 but all the rest of the lines remain the same but if i again do the first one i mentioned but do
#sed 's/www/hello/g' oldfile > newfile
it successfully changes all the www's to hello.
In my books thats strange but like i said im a newbie

Thanks for your swift response Smilie
