Aw: Re: nested while loop doesn't work

[John Kearney]

   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)
   " Maintainer:        Dr. Charles E. Campbell, Jr.
   <NdrOchipS@PcampbellAfamily.Mbiz>
   " Previous Maintainer:    Lennart Schultz <Lennart.Schultz@ecmwf.int>
   " Last Change:        Dec 09, 2011
   " Version:        121
   " URL:
   [1]http://mysite.verizon.net/astronaut/vim/index.html#vimlinks_syntax

   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

   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.)
