Managing dotfiles with DropBox
I'm using DropBox1) to keep personal config files in sync through multiple computers. To do so I need to place the actual files inside the dropbox folder and then symlink them from my homedir.
My setup looks like this:
.gitconfig -> Dropbox/dotfiles/gitconfig .gnupg -> Dropbox/dotfiles/gnupg .ssh -> Dropbox/dotfiles/ssh .vimrc -> Dropbox/dotfiles/vimrc
But these symlinks need to be created on every computer I sync to. And they need to be updated on every computer when a new file or directory is added.
To make this easier, I came up with the following little shell script:
#!/bin/sh cd `dirname $0` F=`pwd |sed -e "s#$HOME/\?##"` for P in * do # skip setup if [ "$P" = "setup.sh" ]; then continue; fi # ensure permissions chmod -R o-rwx,g-rwx $P # skip existing links if [ -h "$HOME/.$P" ]; then continue; fi # move existing dir out of the way if [ -e "$HOME/.$P" ]; then if [ -e "$HOME/__$P" ]; then echo "want to override $HOME/.$P but backup exists" continue; fi echo -n "Backup " mv -v "$HOME/.$P" "$HOME/__$P" fi # create link echo -n "Link " ln -v -s "$F/$P" "$HOME/.$P" done
Now all I have to do is running
Dropbox/dotfiles/setup.sh to update all the symlinks. Should a file or directory already exist, the script renames it before replacing it with the correct symlink.
