<H2>NAME</H2>
ecat - copies file between a domain and STDIN/STDOUT
<A NAME="lbAC"> </A>
<H2>SYNOPSIS</H2>
<A NAME="ixAAC"></A>
ecat -s size [-e][-n][-o][-b] - <I>domain:filename</I>
<P>
ecat <I>domain:filename</I> -
<A NAME="lbAD"> </A>
<H2>DESCRIPTION</H2>
<A NAME="ixAAD"></A>
Similar, but not identical, to UNIX/Linux <TT>"cat"</TT> command.
The main difference is to make <B>ecat</B> symmetrical
with regards to specifying the input and output.
<P>
Exactly two pathnames must be specified,
one of which must be '-',
representing standard-input (<FONT SIZE="-1">STDIN</FONT>) for the first pathname
and standard-output (<FONT SIZE="-1">STDOUT</FONT>) for the second pathname.
<P>
<I>Note on resilience.
Whereas </I><FONT SIZE="-1"><I>ECFS</I></FONT><I> generally tries its best to recover from errors, via retries,
such recovery is often not possible with ecat,
particularly when copying from standard input.</I>
<A NAME="lbAE"> </A>
<H2>OPTIONS</H2>
<A NAME="ixAAE"></A>
<DL COMPACT>
<DT>*<DD>
In the first instance, with the source being <FONT SIZE="-1">STDIN,</FONT>
most options are the same as those in <B>ecp</B>.
There is no '-t'/'-u' option, as there is no timestamp on the source.
<DT>*<DD>
The first instance requires an estimated size, in bytes, for the file.
If this is not accurately known,
then it should be a reasonable estimate.
A slight overestimate is preferable to any underestimate.
<DT>*<DD>
In the second instance, with the destination being <FONT SIZE="-1">STDOUT,</FONT>
there are no useful options.
