Я не большой знаток программирования на bash, но почему for а не while ?

$ man bash

.................................................................................................
while list; do list; done
until list; do list; done
               The while command continuously executes the do list as 
long  as
               the  last  command  in list returns an exit status of 
zero.  The
               until command is identical to the while command, except 
that the
               test  is  negated;  the  do list is executed as long as 
the last
               command in list returns a non-zero exit status.  The exit 
status
               of  the  while and until commands is the exit status of 
the last
               do list command executed, or zero if none was executed.

Это не то, что Вы хотели?
