select specific records from a warts file

## NAME

**sc\_wartsfilter** – select specific records from a warts file

## SYNOPSIS

**sc\_wartsfilter** \[**-a** *address*\] \[**-i** *input-file*\] \[**-o** *output-file*\] \[**-O** *option*\] \[**-t** *record-type*\]

## DESCRIPTION

The **sc\_wartsfilter** utility selects specific records from warts(5) input, and outputs those records. The supported options to **sc\_wartsfilter** are as follows:

- **-a** *address*

  specifies an address or prefix of interest.

- **-i** *input-file*

  specifies the input warts file to process.

- **-o** *output-file*

  specifies the output warts file to write records to.

- **-O** *option*

  allows the behavior of **sc\_wartsfilter** to be further tailored. The current choices for this option are:

  - **check-hops:** Check if an address of an intermediate hop in a trace or tracelb object matches.

- **-t** *record-type*

  specifies a record type of interest. The current choices for this option are:

  - **dealias**

  - **ping**

  - **tbit**

  - **trace**

  - **tracelb**

## EXAMPLES

The command:

sc\_wartsfilter -i input.warts -o output.warts -a 192.0.2.5

outputs all warts records with a destination address 192.0.2.5 from input.warts into output.warts.

The command:

sc\_wartsfilter -i input.warts -o output.warts -a 2001:db8::/32

outputs all warts records with a destination address within the 2001:db8::/32 prefix into output.warts.

The command:

gzcat input.warts.gz \| sc\_wartsfilter -t ping \| sc\_warts2json

selects all ping records from a decompressed input file and and pipes them to sc\_warts2json.
