I'm looking for a method to have bash colorize the output from a command based on what stream it was written to the terminal from. Is there any way to get it to colorize per stream?
Like for example
stdout -> regular color
stderr -> red
program created streams that write to the terminal -> blue
While not identical to your requirements, this earlier question would be worth a read, where someone wanted to differentiate stdout/stderr by color.
There's:
https://github.com/sickill/stderred
or you can do it from bash with something like:
rederror() { (tput setaf 1; cat ; tput sgr0) >&2; }
#Example
someCommand() { echo normal; echo error >&2; }
someCommand 2> >( rederror )
I don't think you can color non-stdout streat that go to the terminal blue from bash. It should be possible with that approach that stderred is using (but I think it only colors stderr).
