Server Environment Files

[devlinjunker]

Is your feature request related to a problem? Please describe:
I would like the experience on remote servers to be as consistent as possible

Describe the solution:
Provide/create .rc files that can be placed on server when sshing to that provide consistent experience

• prompt similar to on my mac, but different enough to differentiate
• run gitstatus in git repos
  • https://github.com/devlinjunker/shell/blob/master/bash/lib/gitstatus
  • (make "leave no trace" mode - cleanup .gitfetch on signout?) -- new issue for this
• network exploration commands
  • from https://github.com/devlinjunker/shell/blob/master/zsh/lib/alias_net.zsh#L17
• store useful commands on the server
  • use @ () { ... } function?

Also would be nice to get information when logging into server

Links/Additional context:
Recent History Script

Testing:

• Place .rc files on amazon server and test that experience is more consistent and helpful info is provided to the user
• ssh to mac mini?
• test on work server?

[devlinjunker]

remember script to show last set of commands run (on login): https://gist.github.com/devlinjunker/42e8ce6bf3cd0eefef966ec49059c605

Setup Script

• Set /etc/hostname
• Set /etc/hosts?
• Set prompt
• Set Aliases
• Check programs installed?

[devlinjunker]

can create file in /etc/profile.d/ (contains scripts that run on each login) to output something...

OR....

on amazon ec2 linux, there is script that runs on cronjob: /usr/sbin/update-motd to update the motd.

• Uses files in /etc/update-motd.d/ to update banner
• see /etc/cron.d/update-motd for cronjob
