For some time, I’ve wanted a backup of my dotfiles, just in case.
Backing up configuration files
I could keep a Git repository, but currently, a simple folder on my laptop, for which I have complete backups via
restic, is good enough for me. I rarely change dotfiles, I prefer using tools that do the heavy lifting for me without too much configuration.
Restoring our configuration
Whenever I need to restore dotfiles, I have this little script that will make symlinks as needed:
#!/bin/bash set -euo pipefail cd dotfiles for f in `find . -type f | sed 's#^./##'`; do # create the directory in which to put the config file's symlink echo -n mkdir $HOME/`dirname $f` read mkdir -p $HOME/`dirname $f` # create the symlink echo -n ln -sf $HOME/dotfiles/$f $HOME/$f read ln -sf $HOME/dotfiles/$f $HOME/$f done cd ..
It shows me what it is about to do, asks for confirmation and then creates the symlink where it should be. For instance,
~/dotfiles/.bashrc gets symlinked to
~/.bashrc. Then, when Bash looks for its configuration, it will to
~/.bashrc which will point to
