Vim

Then see following file to know the categories:

vim /usr/share/vim/vim82/colors/tools/check_colors.vim

And add this code to /usr/share/vim/vim82/colors/elflord.vim. It for the color of column

hi ColorColumn ctermbg=lightgreen guibg=lightgreen

Then, add this code to /usr/share/vim/vim82/colors/elflord.vim. It for unnecessary white spaces

...
hi WhiteSpaces ctermbg=red guibg=red
...

Solved GRUB problem

Make a directory in /boot called efi.

mkdir /boot/efi

Mount EFI disk to /boot/efi

mount /dev/nvme0n1p1 /boot/efi

Then configure grub

grub-install --target=x86_64-efi --efi-directory=/boot/efi/ --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

Now everything is ready with grub. Umount live USB and restart :D

Dart SDK

It usually happens with projects that were created in other machines. To fix this on Android Studio 3.1.3:

1. File-> Settings (ctrl+alt+s)
2. Languages and Frameworks -> Dart
3. Check "Enable Dart support for the project..."
4. In "Dart SDK path" click in "..." and navigate to flutter SDK directory. Under that directory you'll find "bin/cache/dart-sdk". This is the dart sdk path you should use.
5. Click "Apply"
6. Close the project and open it again (sometimes you need this step, sometimes doesn't)

R

• package ‘RGtk2’ (or other) is not available for this version of R:
  • https://rattle.togaware.com/rattle-install-troubleshooting.html
  • Only use install.packages("https://cran.r-project.org/src/contrib/Archive/RGtk2/RGtk2_2.20.31.tar.gz", repos=NULL) and replace https://cran.r-project.org/src/contrib/Archive/RGtk2/RGtk2_2.20.31.tar.gz with the correct package.

Installing RStudio

In this page I found the method to install RStudio https://bbs.archlinux.org/viewtopic.php?id=225057:

Code:

wget https://aur.archlinux.org/cgit/aur.git/snapshot/rstudio-desktop.tar.gz
tar xfvz rstudio-desktop.tar.gz
cd rstudio-desktop
makepkg -si

Install other packages that aren't in pacman repositories

• Search package in https://archlinux.pkgs.org/. Then type:

wget "Binary Package url"

Example:

wget https://aur.andontie.net/x86_64/rstudio-desktop-bin-2021.09.2.382-1-x86_64.pkg.tar.zst

Download tar.gz of packages from ArchLinux

• In package options select Download snapshot.

Remove cache of old applications from wine

rm -f ~/.config/menus/applications-merged/wine*
rm -rf ~/.local/share/applications/wine
rm -f ~/.local/share/desktop-directories/wine*

rm -f ~/.local/share/icons/*-x-wine-*.{xpm,png} }}}

Search text inside of files

• https://ed.team/blog/como-buscar-dentro-de-archivos-en-linux

grep -rni "palabra" .

Change words in multiple files

En el siguiente ejemplo, usaremos sed para reemplazar todas las ocurrencias de la palabra «mongo» por la palabra «aurelio» en todos los archivos que tengan la extensión .txt y que se encuentren en la carpeta /home/usuario/micarpeta/.

find /home/usuario/micarpeta/ -name '*.txt' -exec sed -i "s/mongo/aurelio/g" {} \;

Me di cuenta que es mejor poner el .txt entre comillas, sino find saca errores raros.
