I am having a hard time understanding the dircp script and the dup(3)
device. What's exactly the purpose of writing
@{builtin cd $1 && tar cf /fd/1 .} | @{builtin cd $2 && tar xTf /fd/0}
instead of
{builtin cd $1 && tar c .} | {builtin cd $2 && tar xT}
I also had a look to the pdf2ps script, and there, it seems to be
useful given that you must provide a file trough the option
arguments. But for me this looks like a very narrow application for
the device. What other uses dup(3) might have?
