# Rich Enhanced Shell History
|
|
|
|
Context-based replacement/enhancement for zsh and bash shell history
|
|
|
|
:warning: *Work in progress*
|
|
|
|
## Motivation
|
|
|
|
When you exectue a command in zsh or bash following gets recorded to your shell history:
|
|
|
|
- Command itself
|
|
- Date
|
|
- Duration of the command (only in zsh and only if enabled)
|
|
|
|
But shell usage is contextual - you probably use different commands based on additional context:
|
|
|
|
- Current directory
|
|
- Current git repository/origin
|
|
- Previously executed commands
|
|
- etc ...
|
|
|
|
Additionally it's annoying to not have your shell history follow you accros your devices.
|
|
Have you lost you history when reinstalling? I personally think this is unacceptable in 2019.
|
|
|
|
Why not synchronize your shell history accross your devices and add some metadata to know where it came from:
|
|
|
|
- Hostname
|
|
- Username
|
|
- Machine ID
|
|
|
|
## What this project does
|
|
|
|
Legend:
|
|
|
|
- :heavy_check_mark: Implemented
|
|
- :white_check_mark: Implemented but there are issues
|
|
- :x: Not implemented
|
|
- :zzz: Future ideas - no short-terms plans to implement it
|
|
- :coffee: Working on it!
|
|
|
|
*NOTE: Features can change in the future*
|
|
|
|
- :heavy_check_mark: Record shell history with metadata
|
|
- :heavy_check_mark: save it as JSON to `~/.resh_history.json`
|
|
- save it to a database so we don't have to keep it all in memory
|
|
|
|
- :white_check_mark: Provide bindings for arrow keys - bindings are too slow in bash so they are disabled by default (in bash) when you install resh
|
|
- :heavy_check_mark: imitate default behaviour (at first)
|
|
- :zzz: provide enhanced behaviour
|
|
- :heavy_check_mark: save additional metadata (e.g. command was recalled using arrow keys)
|
|
|
|
- :x: Provide an application like [hstr](https://github.com/dvorka/hstr/) that allows searching history records based on both the command and metadata
|
|
- provide binding for Control+R
|
|
|
|
- :x: Synchronize recorded history between devices
|
|
|
|
- :x: Provide an API to make it possible to write other tools that use the recorded history
|
|
|
|
- :white_check_mark: Show cool graphs based on shell history
|
|
|
|
- :heavy_check_mark: Provide a tool to sanitize the recorded history
|
|
|
|
- :heavy_check_mark: Be compatible with zsh and bash
|
|
|
|
- :heavy_check_mark: Be compatible with Linux and macOS
|
|
|
|
## Data sanitization and analysis
|
|
|
|
In order to be able to develop a good history tool I will need to get some insight into real life shell and shell history usage patterns.
|
|
|
|
This is also my Master thesis so I need to be a bit scientific and base my design decisions on evidence/data.
|
|
|
|
Running `reshctl sanitize` creates a sanitized version of recorded history.
|
|
In sanitized history, all sensitive information is replaced with its SHA1 hashes.
|
|
|
|
If you would consider supporting my research/thesis by sending me a sanitized version of your history then please give me some contact info using this form: https://forms.gle/227SoyJ5c2iteKt98
|
|
|
|
## Prereqisities
|
|
|
|
Standard stuff: `bash`, `curl`, `tar`, ...
|
|
|
|
Additional prerequisities: `bash-completion` (if you use bash)
|
|
|
|
## Installation
|
|
|
|
### Simplest
|
|
|
|
Run this command.
|
|
|
|
```sh
|
|
curl -s https://raw.githubusercontent.com/curusarn/resh/master/scripts/rawinstall.sh | bash
|
|
```
|
|
|
|
### Simple
|
|
|
|
1. Run `git clone https://github.com/curusarn/resh.git && cd resh`
|
|
2. Run `scripts/rawinstall.sh`
|
|
|
|
## Examples
|
|
|
|
Resh history is saved to `~/.resh_history.json`
|
|
|
|
Each line is a JSON that represents one executed command line.
|
|
|
|
This is how I view it `tail -f ~/.resh_history.json | jq` or `jq < ~/.resh_history.json`.
|
|
|
|
You can install `jq` using your favourite package manager or you can use other JSON parser to view the history.
|
|
|
|
|
|
|
|
## Known issues
|
|
|
|
### Q: I use bash on macOS and resh doesn't work
|
|
|
|
**A:** You have to add `[ -f ~/.bashrc ] && . ~/.bashrc` to your `~/.bash_profile`.
|
|
|
|
**Long Answer:** Under macOS bash shell only loads `~/.bash_profile` because every shell runs as login shell. I will definitely work around this in the future but since this doesn't affect many people I decided to not solve this issue at the moment.

## Issues
|
|
|
|
You are welcome to create issues: https://github.com/curusarn/resh/issues
|
|
|
|
## Uninstallation
|
|
|
|
You can uninstall this project at any time by running `rm -rf ~/.resh/`
|
|
|
|
You won't lose any recorded history by removing `~/.resh` directory because history is saved in `~/.resh_history.json`.
