For issues with the vim/gvim highlighting, you'd need to report the
problem in vim, not in bash.

You have a quoting mistake here. "$name" should be quoted, or this will
fail if the variable contains multiple words separate by spaces.

imadev:~$ name="first last"
imadev:~$ [ "ka" = $name ]
bash-4.3: [: too many arguments

This code should work:

while [ "ka" = "$name" ]
do

printf "nothing\n\n"
while [ "ka" = "$name" ]
do
printf "everything\n\n"
done
done

(It goes into an infinite loop when name=ka, but presumably that's what
you wanted.)

as greg say this is the wrong list you need to report this to
" Vim syntax file
" Language: shell (sh) Korn shell (ksh) bash (sh)

the file that does this is /usr/share/vim/vim73/syntax/sh.vim in an
ubuntu system.


and this is probably a simpler example to work with
#!/bin/bash
while true; do
while true; do
done
until true; do
done
done
until true; do
while true; do
done
until true; do
done
done
cheers
