            Bug ID: 224363
           Summary: csh history should not modify >&
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: wosch at FreeBSD.org

I run on a VM:

$ time make buildkernel KERNCONF=GENERIC-NODEBUG >& log.nodebug

later I wanted to do the same on an other VM. I checked the history, did a copy
and paste of the history output of the shell:

$ time make buildkernel KERNCONF=GENERIC-NODEBUG > & log.nodebug

and it failed due the space between ">" and "&", which should be ">&"
I never typed "> &" with a space, this was the csh.

The first VM runs with csh, the second with bash. The bash does not like "> &",
same for the zsh.

I think that the csh history should not insert a space between ">&".

How to repeat:

csh% date >& /dev/null
csh% history | tail -2
   298 17:46 date > & /dev/null
   299 17:46 history | tail -2
