## NAME

sdffilter - manual page for sdffilter 26.11.1

## SYNOPSIS

**sdffilter** \[*OPTIONS*\] *inputFiles*...

## DESCRIPTION

Provides information in a variety of formats (including usda-like) about Sdf Layers or specified (filtered) parts of a layer.

### Positionals:

- inputFiles ...

  The input files to process

## OPTIONS

- **-h**,--help

  Print this help message and exit

- **-p**,--path regex

  Report only paths matching this regex.

- **-f**,--field regex

  Report only fields matching this regex.

- **-t**,--time n or ff..lf

  Report only these times (n) or time ranges (ff..lf) for 'timeSamples' fields

- **--timeTolerance** tol

  Report times that are close to those requested within this relative tolerance. Default: 0.000125

- **--arraySizeLimit** INT

  Truncate arrays with more than this many elements.  If **-1**, do not truncate arrays.  Default: 0 for 'outline' output, 8 for 'pseudoLayer' output, and **-1** for 'layer' output.

- **--timeSamplesSizeLimit** INT

  Truncate timeSamples with more than this many values.  If **-1**, do not truncate timeSamples.  Default: 0 for 'outline' output, 8 for 'pseudoLayer' output, and **-1** for 'layer' output.  Truncation performed after initial filtering by **--time** arguments.

- **-o**,--out TEXT

  Direct output to this file.  Use the 'outputFormat' for finer control over the underlying format for output formats that are not uniquely determined by file extension.

- **--outputType** validity\|summary\|outline\|pseudoLayer\|layer

  Specify output format; 'summary' reports overall statistics, 'outline' is a flat text report of paths and fields, 'pseudoLayer' is similar to the usda file format but with truncated array values and timeSamples for human readability, and 'layer' is true layer output, with the format controlled by the 'out' and 'outputFormat' arguments. Default: outline

- **--outputFormat** TEXT

  Supply this as the 'format' entry of SdfFileFormatArguments for 'layer' output to a file.  Requires both 'layer' output and a specified output file.

- **--sortBy** path\|field

  Group 'outline' output by either path or field.  Ignored for other output types. Default: path

- **--noValues**

  Do not report field values.
