bash-eternal-history

This is a simple filesystem in userspace that contains a single file .bash_eternal_history created for the purpose of storing your bash history indefinitely and across many systems. The filesystem makes use of AWS DynamoDB to store every command entered in bash which may be appended to by multiple sessions simultaneously.

Setup

Download the latest release from GitHub: https://github.com/kurtmc/bash-eternal-history/releases/latest
Create systemd service to automatically mount the filesystem, example configuration:

[Unit]
Description=Mounts bash eternal history

[Service]
Type=simple
Environment=AWS_ACCESS_KEY_ID=XXXXXXXXXXXXXXXXXXXX
Environment=AWS_SECRET_ACCESS_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Environment=AWS_REGION=ap-southeast-2
ExecStartPre=/usr/bin/mkdir -p %h/.bash-eternal-history-fuse
ExecStart=/opt/bash-eternal-history/bash-eternal-history %h/.bash-eternal-history-fuse
ExecStop=/usr/bin/umount %h/.bash-eternal-history-fuse

[Install]
WantedBy=default.target

Create a symlink to .bash-eternal-history-fuse

ln -s -f $HOME/.bash-eternal-history-fuse/.bash_eternal_history $HOME/.bash_eternal_history

Configure bash history in ~/.bashrc, see: https://stackoverflow.com/a/19533853

export HISTFILESIZE=
export HISTSIZE=
export HISTTIMEFORMAT="[%F %T] "
export HISTFILE=~/.bash_eternal_history
PROMPT_COMMAND="history -a; $PROMPT_COMMAND"

Profit.
