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

ovs-parse-leaks
ovs-parse-leaks(8) Open vSwitch Manual ovs-parse-leaks(8)
NAME
ovs-parse-leaks - parses OVS leak checker log files
SYNOPSIS
ovs-parse-leaks [binary] < log
DESCRIPTION
Many Open vSwitch daemons accept a --check-leaks option that writes information about memory allocation and deallocation to a log file.
ovs-parse-leaks parses log files produced by this option and prints a summary of the results. The most interesting part of the output is a
list of memory blocks that were allocated but not freed, which Open vSwitch developers can use to find and fix memory leaks.
The log file must be supplied on standard input. The binary that produced the output should be supplied as the sole non-option argument.
For best results, the binary should have debug symbols.
OPTIONS
--help Prints a usage message and exits.
BUGS
The output can be hard to interpret, especially for a daemon that does not exit in normal operation. Using ovs-appctl(8) to invoke the
exit command that some Open vSwitch daemons support sometimes helps with this.
ovs-parse-leaks usually incorrectly reports one or more ``bad frees of not-allocated address'' errors at the beginning of output. These
reflect frees of data that were allocated before the leak checker was turned on during program initialization.
