SC_WARTS2JSON(1) General Commands Manual SC_WARTS2JSON(1) NAME sc_warts2json -- JSON dump of information contained in a warts file. SYNOPSIS sc_warts2json [file ...] DESCRIPTION The sc_warts2json utility provides a JSON 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 JSON output option had been chosen instead of the warts output option when the data was collected. EXAMPLES The command: sc_warts2json file1.warts file2.warts will decode and print the contents of file1.warts, followed by the con- tents of file2.warts, to standard out. The command: gzcat file1.warts.gz | sc_warts2json will print the contents of the uncompressed file supplied on stdin.

AUTHORS sc_warts2json was written by Matthew Luckie <mjl@luckie.org.nz>. The JSON output formats for traceroute and ping were built on an initial prototype provided by Brian Hammond of Internap Network Services Corpo- ration. The JSON output formats for dealias, tbit, and tracelb were designed and implemented by Matthew Luckie. FreeBSD Ports 14.quarterly March 3, 2023 SC_WARTS2JSON(1)
