 Posted: Thu Mar 03, 2016 11:47 am Post subject: Help!! Good blog/guide to Gentoo tools? eix, qlist, etc.?? |
 |

Hi folks,
I find that I lean very heavily on the output from equery (to supplement emerge). equery has a good man-page and it mostly does what I need... It's also easy to use! 
I will undoubtedly get around to learning about the other tools in app-portage/gentoolkit that I haven't tried...
But there seems to be a myriad of other smaller, single-function tools like qlist , etc. But I can't seem to find anywhere that lists them all - so I can get an overall picture of these and how they fit together... 
Also to find out which ones are depreciated!! 
Then the there is eix... Where even if I Google how to do something with it - I still tend to hit a brick wall!   
I can write reasonably advanced BASH / Awk scripts - but yet I'm really struggling to get my head around eix...
Obviously I've tried the Gentoo Wiki pages first - before posting here... Not looking to be spoon-fed - obviously - but any helpful links would be appreciated!!
Thanks for any insights you can give me!!
Bob

equery f gentoolkit | grep /bin
redo for qlist and friends, but qlist is not in gentoolkit package: equery b qlist
no idea for eix, never had any need for it. |

I do get the impression it would easier - to write a script from scratch to parse the Portage package database - than to learn how to use eix! Glad I'm not alone in having this impression...

Whether you roll your own scripts or make creative use of a lepidoptera, finding the data is rather less difficult than generating the reports in a readily legible manner, that is where existing tools have the advantage. |

BobWya ... there is a lot of duplication in terms of functionality between portage, gentoolkit, portage-utils, and eix, so it somewhat depends on what it is you're looking for, and what particular tools you get accustomed to using. If you're looking for an all encompassing list, and continuity of purpose/use, then you're most likely going to have to lower your expectations ;)
I personally find eix (and eix-* tools) useful, but I'd agree for the most part that you might as well look to the stars as a guide ... all I know about its use has been gleaned from others, and the occasional, often frustrating, perusing of the manpage.

The eix manpage contains all information needed to use eix and should always be accurate for the corresponding eix version. However, with adding of features in eix and changes in portage, the manpage has grown over the years somehow uncontrolled and might deserve a fundamental rewrite: Features/changes had just added/modified where appropriate without restructuring the text as a whole or giving some overview. If nobody steps up, it is doubtfully that this will happen any time soon.

Actually I was hoping that someone might have written a blog post (or similar) with some (useful!!) examples of eix in use... 
I think the only time I've used eix - really - is in a little script I've got to regenerate my world file (from the forums) - from way back, when it got busted by Portage.
Thanks! It does appear I'm not alone then...
Bob

The eix manpage lists some examples near the beginning, and eix-installed-after is meant as such an example (open it with an editor). It all depends on what you want to do... |

BobWya ... in which case you could start a thread in 'Documentation, Tips, and Tricks' for that purpose ... here's one I prepared ealier ;) ... app-portage/eix ... usage, examples, etc
