bash-history

Tools designed to share and improve bash history across sessions and nodes

Current Issues

• history-exporter: When run in a container it does not see commands executed on the host OS. Only the commands executed inside the container are picked up. This might be related to a file system and docker issue. Current the binary needs to be executed on the host OS. iovisor/bcc#2363
• history-exporter: The generated ebpf .o files are still being copied over from cilium/ebpf repo for now.
• history-search: Can run as a container but it might add too much complexity because of how the commands need to be executed within the current shell and not a subprocess.
