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

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
