emerge depclean

I am proud to accept the bone-head award of the day!

I did the ultimate in dumb user / wannabe smart things:

I typed:

You should resurrect the deleted missing libraries, should hope that emerge -u world does this for you (I am not familiar with the -deep option). could also do emerge -p -e world and only compile the packages which are new [N],

Hope you'll fix it,

Cya lX.

Thanks for your kind wishes.

As I understand it, the --deep option tells portage to do a deep dependency scan. At least that's what I think I read... :?:

And if I do an emerge -pe world isn't it going to show me all the packages in my world file as new and if I run that isn't it going to rebuild my entire system? If so, this seems like swatting a fly with a sledgehammer... :?:

I would appreciate any corrections to my thought pattern...

Yes you are completly right, sorry sorry sorry, lack of sleep, ;-)

maybe this script can help:

OK, I am not used to this scripting language. So forgive me if this should be obvious...

See above code...

When running the script, I get the following:

I figured it out. I had copied this to windows notepad to make the file.

I have a whole bunch of ^M return characters that shouldn't be there.

Sorry, for the last post.

Well, as it turned out, the emerge -deep -u world restored most everything...

There were a few programs that were missing in action, such as:

vcron
metalog
reiserfsprogs
progsreiserfs

These were obvious from the boot messages.

There was one other that I found that did not get restored:

libpng (which I found with lx's script -- Thanks lx!

)

[edit]
Well, I still don't have my xterm back so I guess I'm going to have to do a:

Its time to break out the sledgehammer!!!

Well, I think that I pretty much hosed the system so I decided to re-emerge each package so they all get recorded in my world file, so I don't do something like this again...

I made a really crude script to do this for me:

Is your script significantly different from the one that lx posted earlier?

YUP!

I understand mine...

I assume that his was a perl script, which I have not learned yet. It is on the list though...

Also, it should be recording everything in the world file, so if I am dumb enough to repeat my blunder, I should be OK...

I just noticed that there are some things it is lacking, such as mounting /boot so grub can install and that I should have copied my /etc/fstab, /etc/X11/XF86Config, and my other important configs to a safe place, before starting it...

I'm doing all that in vt2 while the script runs in vt1.

Could you post your script here so that others may benefit from it?

See the great big code box I posted above...

I saved it as /usr/portage/rebuildsystem.sh and ran it by typing:

Oh, I'm sorry. I thought that was what your script generated. :oops:

Did you type all that out by hand? You're hardcore.

No I didn't type it by hand. I think I would have just gone for a re-install -- It would be much less typing... :wink:

It is the result of:

This is my script I use to rebuild my whole system it can do a bit of a resume (on packages level), (I use it just for fun, so without damaging my system first ;-)

)

Are you talking about Dolio's
emerge -pe world resuming? I think that's a really great script. I just don't know how well it would work in this situation because I don't think it does any dependancy reconstruction. I also don't really think that your script is much of a hack; it looks pretty clean to me.

Thanks both of you. I have to admit that until I get some time to sit down with the bash documentation, these scripts are pretty greek looking to me.

I can do a basic kix script or dos batch file or even a little VBScript, but I am no programmer. Not yet anyway... :wink:

I have a feeling that as my Gentoo experience progresses, that I will begin to pick up some scripting and programming skills, which I am looking forward to.

I checked the machine this morning and my caveman-ish script is still running, which I expected, as it is just a whole bunch of single commands strung together (I love find and replace). I probably should have attempted some error checking and logging, but I figured that since I was specifying versions that had already been known to install properly on this box, and had already downloaded the tar-balls, that I shouldn't have much difficulty with failures. The only thing that would be likely to fail would be grub, but that is only because /boot is not auto-mounted. I just mounted /boot before I ran the script.

Impatience is the problem for me. You see, I had just finished setting this machine up the night before. I had just managed to get all of my hardware working correctly and software to use the CDR, DVD, Sound, and Video. I went through two weeks of emerging software, configuring, re-configuring and re-configuring until I got it right and BAM! I didn't even get to play with it... sob.

It's a good thing that I actually enjoy blowing away a computer and re-building it, otherwise, this would be unsufferable.

I have one more question that arises from my self-induced fiasco:

Can anyone explain (better that man emerge does) what exactly "emerge depclean" does?

Thanks again!

I have re-visited the man pages, help, and portage guide. Boy do I feel like an idiot. Everything that I have been complaining about is right in front of my nose. I can't figure out why I mis-interpreted them so badly. They are clear as day. :oops:

Examining the Portage manual, I found a switch that would have saved me a bunch of time. --onlydeps

I have no excuse, what is in the man pages and the help says explicitly what will happen if I were to run emerge depclean. I just didn't pay enough attention.
