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?

I also have multiple versions of by bash_profile with syntax specific to the OS. It checks if we're on MacOS or Linux with a kernel check and then reads the appropriate ancillary bash_profile for that platform. Anything that can live in the main bash_profile with the same command on both platforms lives there and anything that needs to be system-specific is in the other one.

I have all my important functions as individual files that get loaded with the following:

function loadfuncs() {
	local funcdir="$HOME/.dotfiles/functions/"
	[ -e "${funcdir}".DS_Store ] &amp;&amp; rm "$HOME/.dotfiles/functions/.DS_Store"
	local n=0

	for i in "${funcdir}"*; do
		source "$(realpath $i)"
		n=$(( n + 1 ))
	done
}
loadfuncs

Interesting way to go about it. Though when I'm at the point where I need differences between linux and darwin, I'm probably going to do that at the home-manager level.

Just for fun, here's how I'm checking that (this was written in 2016 and may require adjusting as I haven't been keeping up on Linux for a while):

function oscheck() {
	if [[ "$(uname -s)" == 'Darwin' ]]; then

		# echo Darwin
		osType=Darwin
		return 0

	elif
		[[ "$(uname -s)" == 'Linux' ]]; then

		# echo Linux
		osType=Linux

		grep CentOS /etc/os-release > /dev/null
		if [[ "$?" == 0 ]]; then
		    # echo "CentOS"
		    export theDistro=CentOS
		    return 0
		else
			:
		fi

		grep Ubuntu /etc/os-release > /dev/null
		if [[ "$?" == 0 ]]; then
		    export theDistro=Ubuntu
		    return 0
		else
			:
			# echo "Not Ubuntu"
		fi

		printf "  %s\n" "Error: osType tested true for Linux, but did not find CentOS or Ubuntu." ""
		return 1

	else
		osType=Unknown
		return 1
	fi
}
oscheck

Checking for Ubuntu or CentOS is a tad limiting given the amount of distros there are ;)

Yeah, but those were the two I was using. I didn't mean to suggest that the code, as is, was correct for everyone. ;-)
