Shared configuration useful for PCDS engineers: "dot" files such as bash configuration (.bashrc) and SSH configuration (.ssh/config).

• Off-site SSH configuration for VPN-free access of PCDS resources.
  • See the next section for what "on-site" and "off-site" mean here.
• On-site bash configuration (~/.bashrc, ~/.bash_profile) with:
  • Detailed descriptions of what each line of what your bash configuration does and how to customize it further.
  • Enables fuzzy-finding of your bash history and files under your path via fzf.
  • Automatically enables EPICS environment access.
  • Automatically allows access to common tools such as engineering_tools and other PCDS-specific scripts.
  • Enables bash tab completion.
  • Provides sample aliases, functions, and helpers for your usage.
  • Configures http_proxy settings on hosts that need it.
  • Disables/reconfigures some functionality that might confuse new - or even well-seasoned users - at times.
  • Closing sections which suggest on how to expand or further customize your settings.
• Sample git configuration (~/.gitconfig) with helpful aliases and pre-configured settings.
• Sample vim configuration (~/.vimrc) with detailed comments indicating why you might want each setting.
• Sample tmux configuration to give you a starting point for your own configuration, with mouse support, additional bindings, and comments to instruct you how to use it.
• Built-in documentation that can be accessed while using shared-dotfiles. (helpme.md)
• Sample conda configuration file for using conda-forge.
• Off-site simple bash settings.

Some configuration is broken up into "on-site" versus "off-site" here.

1. The off-site configuration is meant for your laptop or machine you use at home to connect to the PCDS network by way of SSH, OpenVPN, or similar. It works well on SLAC WiFi, too, so you don't need to switch back and forth.
2. The on-site configuration is meant to be used on PCDS machines like pslogin and psbuild-rhel7. You have a shared home storage space on these machines, so you will only need to install it once.

The off-site configuration is tailored for your use case.

See here for full setup instructions.

• Suggested use for your machine: off-site SSH configuration, and configuration files of your choice
• Suggested use for PCDS machines: on-site configuration installed on, for example, psbuild-rhel7.

Whether you use Windows at home or on-site, you should consider using our pre-configured MobaXterm distribution.

• Suggested use for your machine: You will not need to use the provided off-site configuration here.
• Suggested use for PCDS machines: on-site configuration installed on, for example, psbuild-rhel7.

You can try parts of these settings without installing anything by doing the following:

# Start off on psbuild-rhel7
$ ssh psbuild-rhel7

# Go to your home directory
$ cd

# In your home directory, clone the dotfiles
$ git clone [email protected]:pcdshub/shared-dotfiles dotfiles

# Run the "try me" script which enables access to the bash configuration
# provided by this repository:
$ ./try_me.sh

Please note that this only applies to the bash and vim configuration and not the SSH, git, and other provided configurations here.

If you like the experience provided by these scripts, use the following to source the shared-dotfiles in your current bash configuration:

# Source the 'bash_all.sh' script from shared-dotfiles
$ echo 'source $HOME/dotfiles/on_site/bash_all.sh' >> $HOME/.bashrc

Advanced users may want to start their own dotfiles repository based on this one. We recommend that you version control your dotfiles.

1. Fork pcdshub/shared-dotfiles to your-user/shared-dotfiles

2. $ ssh psbuild-rhel7
   $ cd   # <-- work in your home directory
   $ git clone [email protected]:your-user/shared-dotfiles dotfiles

3. Either use the sourcing method above or refer to .bashrc directly:

   # Use the dotfiles bashrc as your .bashrc
   $ ln -s dotfiles/bashrc .bashrc

Keeping up-to-date with upstream changes will be your responsibility. You may need to rebase or merge with shared-dotfiles as your configuration gets customized.

These dotfiles can be used as your entire configuration, if you are not picky about customizations.

Note that this method includes all customizations provided here: from the bash scripts to vim configuration, and the rest.

To link the scripts and configuration files provided and use them every time when you login:

$ ssh psbuild-rhel7
$ cd
# In your home directory, clone the dotfiles:
$ git clone [email protected]:pcdshub/shared-dotfiles dotfiles
$ cd dotfiles
$ bash use_dotfiles.sh

Please note that the script will not overwrite existing files. You will need to manually move (or less preferably, remove) existing configuration files that are from shared-dotfiles.

You will only need to do this once.

If you've installed or are working in a shared-dotfiles "trial mode", consider typing helpme to view the packaged helpme.md for a reminder on how to navigate directories, find IOCs, and recall what important directories there are.

SSH configurations for on-site versus off-site usage exist.

The use_dotfiles.sh script assumes an on-site configuration for now, so it's recommended to run it on psbuild-rhel7 or similar.
