Re: [Ekiga-list] ekiga -d 4 output is going where?

It is a tricky thing in shell, you need to understand it well.  Here it is.

ekiga writes at descriptor 2.

Your command changes descriptor 2 to use the same as 1, i.e. screen output, afterwards changes the descriptor 1 to use the file. It does NOT changes 2 to be the same as 1!!

Use ekiga -d 4 2>/tmp/ekiga.dmp.

Variations on the same theme also do not produce the expected output as
for example

ekiga -d 4 2>&1 |less

ekiga -d 4  *does* flood the terminal as expected.

echo "testing" 2>&1 >/tmp/test.txt works properly.

echo writes at descriptor 1, hence this works.

I think that I am closing the output stream on ekiga just by choosing
"Quit" from the ekiga menu.

Am I forgetting/overlooking something elementary? I do hope it is not
systemd fouling things up as usual...


PS. The ekiga manual does not seem to mention the ekiga wiki.

Damien, I think we should add it, right?
