History manager for zsh shell with no dependencies.

Merges and deduplicates history entries from ~/.zsh_history, ~/.zsh_history.pre-oh-my-zsh, ~/.bash_history and saves back to ~/.zsh_history.

Creates backup in ~/.zsh_history.bak in case you want to restore.

The order of commands is maintained so latest ones are suggested first.

It may save disk space and redundancy but most importantly you get a specific completion only once as you scroll up in the zsh prompt.

go install github.com/adhocore/zshist

Or, you can also download latest prebuilt binary from release for platform of your choice.

Saved into ~/.zsh_history with 770 commands
