At least the first part -- selecting the category directory -- should become easier, because the possible completion suggestions only involve matching categories rather than all installed matching packages.

But since under Unix/Linux the "/" is used to separate path com- ponents, the build logs in "/var/log/portage/" have sort of ugly names: "category:name-version:MMDD:HHMMSS.log" with a colon rather than a slash between category and name. The "split-log" feature now splits the category to a sub-directory name under "/var/log/portage/build/" and us- es name, version and time stamp as the log file name. This enables you to simply use the full Gentoo package name in scripts as in $ pkg=media-gfx/gimp $ ls /var/log/portage/build/$pkg-*.log | sort -t : -rk 2,3 | head -1 to get the path to the most recent log file without first having to re- place the slash with a colon. This is probably only relevant if you write your own scripts to get your tasks done. And I don't have any idea whether or not it's new, I just found it by pure chance when looking for something else ... :-) Sincerely, Rainer
