The best tip I've come across for maintaining personal preferences across multiple systems is below.

Not really a script, but a `.ssh/config` to automatically deploy parts of my local cli environment to every server i connect to (if username and ip/hostname matches my rules). On first connect to a server, this sync all the dotfiles i want to a remote host and on subsequent connects, it updates the dotfiles. Idk if this is "special", but I haven't seen anyone else do this really and it beats for example ansible playbooks by being dead simple.

Code:

Match Host 192.168.123.*,another-example.org,*.example.com 
User myusername,myotherusername
       ForwardAgent yes       
       PermitLocalCommand yes       
       LocalCommand rsync -L --exclude .netrwhist \
--exclude .git \
--exclude .config/iterm2/AppSupport/ \
--exclude .vim/bundle/youcompleteme/ \
-vRrlptze "ssh -o PermitLocalCommand=no" %d/./.screenrc %d/./.gitignore %d/./.bash_profile %d/./.ssh/git_ed25519.pub %d/./.ssh/authorized_keys %d/./.vimrc %d/./.zshrc %d/./.config/iterm2/ %d/./.vim/ %d/./bin/ %d/./.bash/ %r@%n:/home/%r

What this does, is to copy across the specified files and directories containing your personal preferences to the remote host(s) matching the given IP address(es), hostnames and user(s) on first login and updates them on subsequent logins.

It just really runs an rsync command as specified on successful login.

Here is my simple prompt:

Code:

set prompt="$host % "

I spent a little time trying to make this more understandable (to me)

Code:

# set command prompt
# re:https://linux.101hacks.com/ps1-examples/prompt-color-using-tput/

RED=`tput setaf 1`
GREEN=$(tput setaf 2)
REVERSE=$(tput rev)
OFF=$(tput sgr0)

PS1=$REVERSE$GREEN"\@:"$OFF    # time in AM/PM format
if [[ ${EUID} == 0 ]] ; then   # if we are "root"
    PS1+=$RED                  # set USER to display in RED
else
    PS1+=$GREEN                # set USER to display in GREEN
fi
PS1+=" \u@"$REVERSE"\h:\W"$OFF  # display USER@HOSTNAME plus CWD
PS1+=" \!: \$ "              # display current history number + prompt 

export PS1                     # export the prompt string

I used the bash syntax += to build the PS1 variable in sections so I could understand what each section is trying to do and comment it so I could understand what I did later.

You need a dotfile manager. I use GNU Stow. Other projects are listed here:

Never thought about it. Always used the default prompt with no need to change. Host and directory info is important to me. The Host in the prompt tells me what machine I am ssh'd into. Otherwise it would be very confusing with several terminals open looking at different machines (say a bunch of RPIs, server, desktops, laptops) with some having split views...

My favorite Linux prompt is the good old # or hash mark coupled with bash.

Code:

[neofetch

Yeah I know what you guys and gals are thinking: why do you have an Xeon-based Workstation as a Daily driver? To that query, I'd answer that I take full advantage of the "overbuilt" machine as a general-purpose daily and multipurpose virtualization platform.
