Bash script for updating and mantaining gentoo install

[InvisibleRasta]

Hello guys, i tend to forget the commands needed to mantain my system so i wrote a script for updating and such. I tought i could share it so you guys can use it to or perhaps give me some suggestions.

So here it is:

https://gist.github.com/InvisibleRasta/fdb6607510a820628c693d8baad0f52c

A little description of what it does:
For each of these commands it will print a description of what they do.
You can press Yy or Enter for yes or Nn for no.
If you press no it will skip to the next option.
You can change the order of the commands if you would like. This is how i tend to run them.

eix-sync
revdep-rebuild -v
emerge -uDNqva @world
emerge -pac
etc-update
eclean-pkg
eclean-dist

EDIT: I also added a news read command at the end.
eslect news read

Hello.

For my own I prefer command to be completed from history search, but I'll give you my 2 cents anyway.
What bothers me a little with your script is the necessity to pass the whole loop of Y/N, and where in the loop you placed the revdep-rebuild.
I would rather have each command wrapped in a function (sync -> eix-sync || exit $?) and loop through command line optionsusing[/list] a switch statement with each desired function mapped to an option, allowing command line options like 'sync update depclean', as well as any shortcut option you may want to define. For example, I would have:
- syncup: eix; update (I prefer dealing with etc-update first after an update, then no depclean in my shortcut)
- etc
- depclean
- revdep
- eclean: ecleanpkg; ecleandist
You may also add help and/or list options and functions as a self reminder.
Cherry on top of the cake, you avoid the use of eval command.

Hello,

First of all, thanks for sharing the script.

In my case I follow a different approach:

FWIW, my routine. I have a different way to effect the "ask" before proceeding.

First get a new portage tree. $(emerge --sync) hooks to eix via a small script /etc/portage/postsync.d/eix-update -- more on that later.
