Unfortunately, there's a small logical flaw in above; the sequence of files and thus how the arrays are populated DOES matter. Try
Code:
awk '
       FILENAME=="b" {arr[$0]++; next}
       FILENAME=="a" {if( !arr[$0] ) srch[$0]++}
       FILENAME=="c" {if(srch[$2]) print}
      '  b a c
test test.rpm


EDIT: How about
Code:
grep $(diff -y -b --suppress-common-lines a b | cut -f1) c
test test.rpm

File Compare and Create New File with Diff

I need to compare File A with File B and create FILE C with the difference record only. What I mean is File A has 3 records and File B has 4 records, so FILE C will only have 1 record (becuase that record is in FILE B and not in File A). Hope I am making sense. The data layout is that each data... (7 Replies)

gnunet-transport(1)					      General Commands Manual					       gnunet-transport(1)

NAME

       gnunet-transport - measure and control the transport subsystem

SYNOPSIS

       gnunet-transport [OPTIONS]

DESCRIPTION

       gnunet-transport  is  a	tool  to  access  various  functions of GNUnet's transport subsystem from the command-line.  Most of these are not
       expected to be useful for end-users.  gnunet-transport can be used to evaluate the performance of the transports, force a peer  to  connect
       to another peer (if possible).  Other functions should be added in the near future.

       -b, --benchmark
	      measure  how  fast  we are receiving data (from all connections).  On exit, the data rate will be reported.  Runs until aborted with
	      CTRL-C.

       -c FILENAME, --config=FILENAME
	      configuration file to use

       -C PEER, --connect=PEER
	      peer to connect to (and to use for sending if used in conjunction with -s)

       -h, --help
	      print help page

       -i, --information
	      print information about our current connections (once)

       -m, --monitor
	      print information about our current connections (continuously)

       -L LOGLEVEL, --loglevel=LOGLEVEL
	      Change the loglevel.  Possible values for LOGLEVEL are ERROR, WARNING, INFO and DEBUG.

       -s, --send
	      transmit (dummy) traffic as quickly as possible to the peer specified with the -C option.  The rate will still  be  limited  by  the
	      quota(s)	determined  by	the  peers (ATS subsystem).  Will run until CTRL-C is pressed or until the connection to the other peer is
	      disrupted.

       -t, --test
	      test transport configuration.  With this flag, the tool will check if each  of  the  configured  transport  plugins  has	a  working
	      address.	 Plugins  that	do  not have a listen port configured will be ignored.	The test is performed with the help of an external
	      server (by default running on gnunet.org) which tries to contact the local machine.  The test can only work if the local GNUnet peer
	      is not yet running.

       -v, --version
	      print the version number

       -V, --verbose
	      be verbose
