RAGREP(1)		     General Commands Manual		       RAGREP(1)

NAME
     ragrep - grep argus(8) user captured data.

SYNOPSIS
     ragrep [options] -e pattern [raoptions] [-- filter-expression]
     ragrep [options] -f file	 [raoptions] [- filter-expression]

DESCRIPTION
     Ragrep  reads argus data from an argus-data source, greps the records based
     on the regexp specified on the command line, and  outputs	a  valid  argus-
     stream.

     Ragrep  works  only  on  the  fields  for user captured data. Argus must be
     started with the configration option ARGUS_CAPTURE_DATA_LEN set to a  value
     greater than 0, to have these data captured. See argus.conf(5) for detail.

     Ragrep  is  based	on  GNU grep(1), so the regexp syntax is the same as for
     grep(1).

OPTIONS
     Ragrep, like all ra based clients, supports a number of ra options  includ-
     ing  filtering  of input argus records through a terminating filter expres-
     sion.  See ra(1) for a complete description of ra options.  ragrep(1)  spe-
     cific options are:

     -c  Suppress  normal  output;  instead  print a count of matching lines for
	 each input file.  With the -v, --invert-match option (see below), count
	 non-matching lines.

     -e <regex>
	 Match regular expression in flow user data fields.  Prepend  the  regex
	 with  either  "s:"  or  "d:" to limit the match to either the source or
	 destination user data fields.	Examples include:
	    "^SSH-"	      - Look for ssh connections on any port.
	    "s:^GET"	      - Look for HTTP GET requests in the source buffer.
	    "d:^HTTP.*Unauth" - Find unauthorized http response.

     -f FILE
	 Obtain patterns from FILE, one per line.  The empty file contains  zero
	 patterns, and therefore matches nothing.

     -i  Ignore case distinctions in both the PATTERN and the input files.

     -L  Suppress  normal output; instead print the name of each input file from
	 which no output would normally have been printed.   The  scanning  will
	 stop on the first match.

     -l  Suppress  normal output; instead print the name of each input file from
	 which output would normally have been printed.  The scanning will  stop
	 on the first match.

     -q  Quiet; do not write anything to standard output.  Exit immediately with
	 zero status if any match is found, even if an error was detected.

     -R  Read all files under each directory, recursively; this is equivalent to
	 the -d recurse option.

     -v  Reverse the expression matching logic.

DIAGNOSTICS
     Normally,	exit  status is 0 if selected records are found and 1 otherwise.
     But the exit status is 2 if an error occurred, unless the -q option is used
     and a selected line is found.

INVOCATION
     A sample invocation of ragrep(1).	This call reads argus(8) data  from  in-
     putfile  and  greps  all http transactions that generated a "404 Not Found"
     error.

     ragrep -r inputfile -e "HTTP.*404"
