brilliant.

just need to output to file now.
thought a simple > out would do but

Code:
#!/bin/bash
awk 'FILENAME=="target" {arr[$0]++}
        FILENAME=="lookup" { if (!($0 in arr))
        {print $0 > out}}' target lookup
exit 0

awk: cmd. line:3: (FILENAME=lookup FNR=1) fatal: expression for `>' redirection has null string value

gnunet-rsa

GNUNET-RSA(1)						      General Commands Manual						     GNUNET-RSA(1)

NAME

       gnunet-rsa - manipulate GNUnet RSA key files

SYNOPSIS

       gnunet-rsa [options]FILENAME

DESCRIPTION

       gnunet-rsa  can	be used to create an RSA private key and to print the corresponding public key.  You must specify a filename containing an
       RSA private key in GNUnet format as an argument.  If the file does not exist, gnunet-rsa will create a key.  This may then  take  a  while.
       If the option -p is given, the corresponding public key will be printed to the console.

OPTIONS

       -p, --print-public-key
	      Print the corresponding public key to stdout.

       -P, --print-peer-identity
	      Print the corresponding peer identity (hash of the public key) to stdout.  This hash is used for the name of peers.

       -s, --print-short-identity
	      Print the corresponding short hash (256-bit hash of the public key) to stdout.  This hash is used for names in the zkey zone.

       -c FILENAME,  --config=FILENAME
	      Use the configuration file FILENAME.

       -h, --help
	      Print short help on options.

       -L LOGLEVEL, --loglevel=LOGLEVEL
	      Use LOGLEVEL for logging.  Valid values are DEBUG, INFO, WARNING and ERROR.

       -v, --version
	      Print GNUnet version number.
