 |
|
| I'm going to be doing a big update and I want to do emerge through screen(because I'm doing it over SSH). Is there any way that I can have it log whats going on because if it errors out I want to know what did and why. |

| Code: | | emerge foo 2>&1 | tee logfile.txt |
See also the various LOG variables in /etc/make.conf.example (I prefer a manual tee, myself)

That will get me a huge log file though won't it? Is there any way I can get it to do just the errors or better yet the last, say 10 lines before it exits.
EDIT: Also out of curiousity why to you need the 2>&1? wouldn't it work the same without it? |

With gnu screen you can use CTRL+a+H to log everything whats going on in the screen window to ~/screenlog.<window_number> ... besides that I really recommend to dive into the LOG variables in /etc/make.conf.example and/or use something like enotice which helps you keeping track of all the messages an emerge process is producing.

The 2>&1 logs stderr to the same place stdout goes. You would need this if you want to see things printed out the stderr. |
