Notes:

I haven't made any open-source contributions for some time,
although I intend to rectify this over the next several months.



Perhaps the most important contribution that I've made was
having the idea[1] to dual-license Mozilla as a way out of
the GPLNPL dilemma. My proposal was well received but not
implemented at the time (in particular, jwz wasn't
convinced), but some of those at Netscape who were convinced
were able to act on it after jwz left, which gave us the
now-widely-used MPL-1.1 and Mozilla (and later Firefox) able
to be linked with code under the Gnu GPL.

Prefixing stdout and stderr with helpful markers

I’m testing a piece of logging code, so I care a lot about what goes where. I figured that there had to be a shell one-liner to allow me to mark stdout/stderr without any setup or code changes. Here it is:

(( some_command | sed '-es/^/stdout: /' >&3 ) 2>&1 | sed '-es/^/stderr: /') 3>&1

So, for a trivial example:

$ ((( echo out ; echo err >&2; ) | sed '-es/^/stdout: /' >&3 ) 2>&1 | sed '-es/^/stderr: /') 3>&1
stderr: err
stdout: out
$

As the example shows, sequence between stdout and stderr may not be preserved.
