Normally I would start a command like
longcommand &;
I know you can redirect it by doing something like
longcommand > /dev/null;
for instance to get rid of the output or
longcommand 2>&1 > output.log
to capture output.
But I sometimes forget, and was wondering if there is a way to capture or redirect after the fact.
longcommand
ctrl-z
bg 2>&1 > /dev/null
or something like that so I can continue using the terminal without messages popping up on the terminal.
