Cut and paste in Linux?

So what I am trying to do is cut the fifth field from a fixed length record and paste it into the first field using a single line command. I am attempting to do this using a pipe and having no luck thinking of the second command to use. Probably something simple I am just overlooking, thanks in advance. The command I have so far is...

cut -c26-35 file | {Hamster stops turning the wheel at this point}
