 |
|
Hi.
I am a newbe to linux.
As root I accidentaly entered: PORTDIR_OVERLAY="/usr/portage/local/layman/wschlich-testing"
I was suppsosed to enter this in /etc/make.conf, and did so afterwards.
When I entered: PORTDIR_OVERLAY="/usr/portage/local/layman/wschlich-testing" as root in the terminal all that happened was I got a new line, localhost torleif #
There was no error message. Usually when I type somthing wrong it says "command not found"
since it did not say "command not found", did it do something? if so what?
Another question?
If I do "emerge -ae world" I get a lot of packages that needs to be rebuil. I said no.
What does "emerge -e world" do?
Regards
Torleif |

Okay - First thing first - when you do something="a string", it sets the environment varible something to "a string". After doing that command, nothing was technically wrong. You could have used it just fine. All make.conf does is set those variables automatically, and across sessions. Try echoing $PORTDIR_OVERLAY .
In emerge -e, the "e" stands for every - as in, emerge -e world compiles every package in world.
Quick tips:
To update: emerge -uDNav world
To emerge something: emerge -av package
And ALWAYS: revdep-rebuild

Simply
| Code: | | unset PORTDIR_OVERLAY |
to undo your previous command. This is safe since that particular environment variable is supposed to be set by each new emerge session, not inside a login shell. |

Nothing permanent. If you've already rebooted the system, or logged out/back into that shell, nothing is left of your mistake.

It's more than that. "-e" stands for "empty tree": emerge this package and every package that it depends on. So "emerge -e world" means basically "recompile every package on your computer". |
