parse a file and fill an array with it

Hi Guys,

I am trying to do a file parse which is something like

config file:
machines= sha1 sha2 sha3 sha4

The bash script should be supporting upto 64 such machines
what I want is to place the machines in an array and then use the array to ssh to each machine.

The script I worte

declare -x machine
x=$(gawk -F ' ' '/^machine/ {print NF}' a)
i=1

while [ $i -lt $x ]; do
machine=$(gawk 'BEGIN {FS=" "} ; /^machine/ && NF <= 64 {print $i}' a)
#do the SSH here
let "i+=1"
echo mach $machine
done

The script always prints the entire line instead of indivudual word.
Also, it only works if there a single entry of 'machine'

Can some please help in this.

Cheers,
nani

cs_destroy(3)							      cs/cs.h							     cs_destroy(3)

NAME
cs_destroy - clean up and dealloc a parse tree SYNOPSIS
#include <cs/cs.h> void cs_destroy (CSPARSE **parse); ARGUMENTS
parse - a pointer to a parse structure. DESCRIPTION
cs_destroy will clean up all the memory associated with a CSPARSE structure, including strings passed to cs_parse_string. This does not clean up any memory allocated by your own CSOUTFUNC or the HDF data structure passed to cs_init. It is safe to call this with a NULL pointer, and it will leave parse NULL as well (ie, it can be called more than once on the same var) RETURN VALUE
parse - will be NULL SEE ALSO
