HI Any sed gurus on the list? I use it often in a class I am taking but I am stuck on this one and have had no luck with the docs I have found. What I need to do is append 'z=z+' to the beginning of every line in a file. The file looks like this: 1234960 1456780 3456567 5476865 456098 thats it 1 simple column! Maybe I need some sleep it is 1 am here in Germany. Thanks for any help! (I know you are out there der hans) :)
