Is it possible to log all stdout and stderr to a file? [RESOLVED]
I want to create a large log file for everything printed to stdout and stderr (separately, preferably) that is owned (might be the wrong terminology) by my user or the root. The idea is that I could run a program from the terminal like normal, and everything it printed would also be written to this log file. Is there a way to do this? It seems like something that a lot of people would have a use for.

The simplest / manual way would be to use tee:
some-command-here 2>&1 | tee -a /path/to/logfileIf there were specific commands you wanted to log, this could work well. But for every command typed directly in an interactive shell, you'd be better off using the `script' tool perhaps launched from your shellrc.
As for anything outside of an interactive shell, this would be highly impractical and likely be a very bad idea. Most of that is logged somewhere already (mostly the journal nowadays).

You want all output written to the terminal but stderr and stdout also logged to separate files so are you asking for something like?
some-command-here 2> >(tee stderr.log) > >(tee stdout.log)Offline

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
