From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sync bash aliases and ssh keys across devices (lemdro.id)

How do you guys quickly sync your settings (especially bash aliases and ssh keys) across your machines?

Ideally i want a simple script to run on every new server I work with. Any suggestions?

On my devices like PCs, laptops or phones, syncthing syncs all my .rc files, configs, keys, etc.

For things like servers, routers, etc. I rely on OpenSSH's ability to send over environmental variables to send my aliases and functions.
On the remote I have
[ -n "$SSH_CONNECTION" ] && eval "$(echo "$LC_RC" | { { base64 -d || openssl base64 -d; } | gzip -d; } 2>/dev/null)"
in whatever is loaded when I connect (.bashrc, usually)
On the local machine
alias ssh="$([ -z "$SSH_CONNECTION" ] && echo 'LC_RC=$(gzip < ~/.rc | base64 -w 0)') ssh'

That's not the best way to do that by any means (it doesn't work with dropbear, for example), but for cases like that I have other non-generic, one-off solutions.
