In other words, the actual lines look more like this:

Code:
-file1 a001.txt -file2 b001.txt -outputx xa001b001 -outputy ya001b001
-file1 a001.txt -file2 b002.txt -outputx xa001b002 -outputy ya001b002
-file1 a001.txt -file2 b003.txt -outputx xa001bl003 -outputy ya001b003

As you can see, the current script would change the numbers for a (as intended) but also the corresponding number for b.

Not sure I get it - do you want the "a" numbers modified in the the file, or work on the file names starting with "a" only? I case of the former, try gsub (/a001/, "a" TCNT, T), in case of the latter, try a*.txt for the file name parameter.

sc_warts2text

SC_WARTS2TEXT(1)					    BSD General Commands Manual 					  SC_WARTS2TEXT(1)

NAME

     sc_warts2text -- simple dump of information contained in a warts file.

SYNOPSIS

     sc_warts2text [-d ip2descr-file] [file ...]

DESCRIPTION

     The sc_warts2text utility provides a simple dump of information contained in a sequence of warts files.  The output is the same as that which
     would have been provided by scamper if the text output option had been chosen instead of the warts output option when the data was collected.
     The options are as follows:

     -d ip2descr-file
	     specifies the name of a file with IP-address, description mappings, one mapping per line.	See the examples section for further
	     information.

     While the output of sc_warts2text is structured and suitable for initial analyses of results, the format of the output is not suitable for
     automated parsing and analysis as the output of sc_warts2text will change overtime with no regard to backwards compatibility.  Analyses of
     the contents of a warts file should be made using specialised programs which link against the scamper file API.

EXAMPLES

     The command:

	sc_warts2text file1.warts file2.warts

     will decode and print the contents of file1.warts, followed by the contents of file2.warts.

     The command:

	gzcat file1.warts.gz | sc_warts2text

     will print the contents of the uncompressed file supplied on stdin.

     Given a set of IP-address, description pairs in a file name mappings.txt:

	192.0.2.1 "foo"
	192.0.2.2 "bar"

     then the command gzcat file1.warts.gz | sc_warts2text -d mappings.txt will print the description associated with a given destination address
     before each result is presented.
