How to reference a personal folder of icons for the system ?

[mIROUZ]

Hi,

I created a folder with my PNG icons inside :

Code: Select all

# mkdir /usr/share/icons/myicons

But if I type a search by name of my icons in the icon selection pane of a folder's properties, my icons don't show up.

Is there an index to refresh so that the system takes into account my new folder of icons ?

thank you

The search covers in the first place your home, but /usr does not belong to that. Besides that is /usr (and everything below) a bad place for your own files, because /usr gets managed by the package management and it is at every time possible, that your files get deleted without warning.

Why did you choose this place, what is your goal?

[mIROUZ]

This is because if I drop my personal icon folders in "home/my_account/..." then I don't have the power to change the icon of "my_account" itself, because it is a level tree structure which still depends on the authority of root.

Then you should at least put your icons in a folder below the /opt branch, to solve the problem, that I mentioned. That does not solve your main question, of course. (Actually, I never use Nemo for searching, so I do not know possible problems.)

It's a good idea but it's surprising because looking at it I don't have the opt branch.
I am on Ubuntu based distro.

Try this tutorial https://wiki.archlinux.org/title/icons and see if it works for your purpose?

Some sample code copied from that page:

Code: Select all

xdg-icon-resource install --size 128 --context emblems archuser-example.png
xdg-icon-resource install --size 128 archuser-example.png
xdg-icon-resource install --size 128 --context mimetypes application-x-keepass2.png

If you got a lot of icons, they also suggested

Move the extracted folder containing the icons.
> /usr/share/icons/ (system-wide), or:
> ~/.icons/ or ~/.local/share/icons/ (user only).
Optionally run gtk-update-icon-cache -f -t on the directory that you chose to update the icon cache.

Ok i will look at that, thank you

Every time I reopen the icon selection system the system still shows me /usr/share/icons.
It's annoying to re-navigate to my home folder all the time.
Is it possible to determine another address to present by default for the icons ?

[mIROUZ]

Well, it apparently says it's good to put it in /usr/share/icons.
If really one day after a migration or other my file disappears then I would change.
For the moment I will do like this because it is the most practical and effective that I have observed.

Thanks to you for helping me.

Every time I reopen the icon selection system the system still shows me /usr/share/icons.

Those installation instruction are supposed to replace the whole icon theme, or let one select the installed icon theme in Menu > Themes > Icons

Meanwhile the xdg-icon-resource command is also supposed to replace icons of the same name within the existing icon theme, not for "I want this folder use custom icon x". However, there's the stupidity of "xdg-icon-resource" never support .svg files when there are a lot of icon themes using them and all the DEs are running them merrily.

If /opt is (not) yet there - this happens, as long there was no need for it - create it:

Code: Select all

sudo mkdir /opt

@Cosmo
Do you think it is better to create OPT in Su or in Sudo ?
I have the impression that the privileges (bin) are different depending on the way ?

@billyswong
Thank you
I enjoyed reading your article.

Sorry, my fault. I updated my advice (with sudo).

[mIROUZ]

Ok thanks
