Error
zsh: corrupt history file /home/u_walkews/.zsh_history
Dammit I don’t want to redo my shell history, I checked with a clanker and they
came up with this solution using strings that only prints printable
characters.
cp ~/.zsh_history ~/.zsh_history.bak
mv ~/.zsh_history ~/.zsh_history.corrupt
touch ~/.zsh_history
chmod 600 ~/.zsh_history
strings ~/.zsh_history.corrupt > ~/.zsh_history
chmod 600 ~/.zsh_history
Stow comes with a local and global ignore list that you can use to ignore certain files or directories.
If you put Perl regular expressions, one per line, in a .stow-local-ignore file within any top level package directory, in which case any file or directory within that package matching any of these regular expressions will be ignored. In the absence of this package-specific ignore list, Stow will instead use the contents of ~/.stow-global-ignore, if it exists. If neither the package-local or global ignore list exist, Stow will use its own built-in default ignore list, which serves as a useful example of the format of these ignore list files:

gpus are awesome and I need one for Bambu Studio to be usable in a
distrobox. Adding the --nvidia flag to distrobox create bind mounts the
nvidia /dev/ devices and sets up the necessary environment variables. Once
we are in there are a couple of packages to install to make it work.
distrobox create --name bambu-studio --image archlinux:latest --nvidia
distrobox enter bambu-studio
sudo pacman -S nvidia-utils lib32-nvidia-utils vulkan-icd-loader
nvidia-smi
glxinfo | gprep OpenGL
sudo pacman -Syu --needed base-devel git
git clone https://aur.archlinux.org/paru-bin.git
cd paru-bin
makepkg -si
paru -S bambustudio-bin
bambu-studio
distrobox-export --app bambu-studio
Today I learned how to use tar over ssh to save hours in file transfers. I keep all of my projects in ~/git (very creative I know, I’ve done it for years and haven’t changed). I just swapped out my main desktop from bazzite to hyprland, and wanted to get all of my projects back. Before killing my bazzite install I moved everything over (16GB of many small files), it took over 14 hours, maybe longer. I had started in the morning and just let it churn.
This was not going to happen for re-seeding all of my projects on my new system, I knew there had to be a better way, I looked at rsync, but for seeding I ran into this tar over ssh technique and it only took me 6m51s to pull all of my projects off of my remote server.
ssh [email protected] 'tar -C /tank/git -cpf - .' \
| tar -C "$HOME/git" -xpf -
Today I needed to make a backup of some config. I wanted to add a timestamp so that I knew when the backup was made. This would make unique backups easy, and I could tell when they were made.
cp configfile configfile.backup.$(date %s)
If you want to decrypt the timestamp into something more human readable. You can list backup files, strip out the timestamp, and then convert it to a human readable date.
/bin/ls | grep backup | sed 's/configfile.backup.//' | xargs -I {} date -d @{}
or just throw it to the date command by hand.
date -d @1755895402
I’ve got a few samba shares going in my homelab, and I’m struggling finding a great app to scroll through vacation photos with my wife. I want something intuitive, non intimidating, and just works. Turns out that the default file browser application for hyprland works great, but you need to enable previews for remote storage for it to work for my use case here.
I am a linux user through and through. Desktop, server, vms, containers,
everything except my phone is linux. With this I spend a lot of time in the
terminal, and have been a long time user of !! to rerun the last command, but
with the ability to tack something on at the beginning or end.
TIL about fc, which opens the last command in your shell history in your
$EDITOR or pass in your editor -e nvim.
!! pronounces bang bang and will run the last command in your history.
ls -l
!! | wc -l
# ls -l | wc -l
sudo !!
# sudo ls -l | wc -l
!!:s/-l/-l \/tmp
# sudo ls -l /tmp | wc -l
fc enters the chat #Now making complex edits in your shell can be a bit of a chore, so fc moves
this work to your $EDITOR.
fc
This pops open your $EDITOR with the last command in your history.
sudo ls -l | wc -l
fc shows up in shell history, but !! does not, !! gets replaced by the
command that it becomes.
yaya yaya, I know you can also up-arrow c-e, but what fun is that, it’s barely a
flex. fc just looks big brained and like you really know what you are doing.
