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.
