simple and small question

if i type 'red' at a bash prompt, then whenever i type anything more in, it outputs ? :

Code:

drigz@ayro:~$ red

help

?

exit

?

version

?



?

that was control+c

?

quit

?

and i have to close the console to quit. this is the help:

Code:

drigz@ayro:~$ red --help

Usage: red [OPTION]... [FILE]



  -G, --traditional          use a few backward compatible features

  -p, --prompt=STRING        use STRING as an interactive prompt

  -s, -, --quiet, --silent  suppress diagnostics

      --help                display this help

      --version              output version information



Start edit by reading in FILE if given.  Read output of shell command

if FILE begins with a `!'.

what is this program? theres no man page, nothing i can find (red is hardly definitive for a google search). does anyone know?

btw this is purely curiosity.

From man red:
