.SH NAME
desync-cat - Stream a blob to stdout or a file-like object


.SH SYNOPSIS
\fBdesync cat <index> [<output>] [flags]\fP


.SH DESCRIPTION
Stream a blob to stdout or a file-like object, optionally seeking and limiting
the read length.

.PP
Unlike extract, this supports output to FIFOs, named pipes, and other
non-seekable destinations.

.PP
This is inherently slower than extract as while multiple chunks can be
retrieved concurrently, writing to stdout cannot be parallelized.

.PP
Use '-' to read the index from STDIN.
