That is the purpose of the IFS. You can directly process the file seperated by '^' so and not have to bother with having to use things like cut and awk.

As an example:
Code:
#!/bin/ksh
IFS='^'
while read x y z; do
echo $x $y $z
done < tmp.tmp

tmp.tmp:
a^b^c
d^e^f
i^j^k

NAME

       phones - remote host phone number database

SYNOPSIS

       /etc/phones

DESCRIPTION

       The  file /etc/phones contains the system-wide private phone numbers for the tip(1) program. /etc/phones is normally unreadable, and so may
       contain privileged information.	The format of /etc/phones is a series of lines of the form:

       <system-name>[ 	]*<phone-number>.

       The system name is one of those defined in the remote(4) file and the phone number is constructed from [0123456789-=*%]. The  `='  and  `*'
       characters  are	indicators  to	the auto call units to pause and wait for a second dial tone (when going through an exchange).	The `=' is
       required by the DF02-AC and the `*' is required by the BIZCOMP 1030.

       Comment lines are lines containing a `#' sign in the first column of the line.

       Only one phone number per line is permitted. However, if more than one line in the file contains the same system name tip(1)  will  attempt
       to dial each one in turn, until it establishes a connection.

FILES

       /etc/phones
