Arguments to awk
I have an awk script where I pass some arguments

For example I will call awk in this fashion

Code:
awk -v anomaly=nAmon/pAnom -v aloc=zmin/ztran/zmax -v modeldepth=modeldepth

My problem is that I want to have the option to pass the variable anomaly in two ways.

Either using

Code:
-v anomaly=nAmon/pAnom

or using

Code:
-v anomaly=amon

Thus I need to distinguish what the user has inputted and then do the appropriate stuff depending on which version he's using.

TRACERTSTATS(1) 						   User Commands						   TRACERTSTATS(1)

NAME

       tracertstats - perform simple filter based analysis on a trace

SYNOPSIS

       tracertstats  [	-f  |  --filter bpf ] [ -i | --interval interval ] [ -c | --count count ] [ -o | --output-format csv,txt,png,html ] [ -m |
       --merge-inputs ] inputuri...

       tracertstats -H|--libtrace-help

DESCRPTION

       tracertstats takes a list of bpf expressions and outputs the number of packets and bytes that match that expression every interval seconds,
       or count packets.

       -f bpf-filter
       --filter bpf-filter
	      Add another "bpf filter"

       -i interval
       --interval interval
	      Output results every interval seconds.

       -c count
       --count count
	      Output results every count packets.

       -m
       --merge-inputs
	      Treats  all inputs as a single input, resulting a single unified output rather than an output for each input. Works best with traces
	      that are consecutive to create a single CSV, for instance.

       -o format
       --output-format format
	      Selects the output format.

	      txt    Human readable text.  This is the default output format which provides output easily understood by a human.  This format  has
		     the disadvantage that it takes up quite a bit of horizontal space.

	      csv    Comma Seperated Values. This is suitable for further analysis in a spreadsheet, or other program.

	      png    PNG Graphic.  Produces a fairly incomprehensible png graph.  This relies on gdc being available at compile time.

	      html   This produces output suitable for display to a human in a webbrowser.

EXAMPLES

       tracertstats --filter 'host sundown' 
	    --filter 'port http' 
	    --filter 'port ftp or ftp-data' 
	    --filter 'port smtp' 
	    --filter 'tcp[tcpflags] & tcp-syn!=0' 
	    --filter 'not ip' 
	    --filter 'ether[0] & 1 == 1' 
	    --filter 'icmp[icmptype] == icmp-unreach' 
	    --output-format html
	    erf:/traces/trace1.gz 
	    erf:/traces/trace2.gz
