SANITIZATION In sanitized history, all sensitive information is replaced with its SHA1 hashes $ reshctl sanitize If you would consider supporting my research/thesis by giving me a sanitized version of your history then please give me some contact info using this form: https://forms.gle/227SoyJ5c2iteKt98 ARROW KEY BINDINGS Resh provides arrow key bindings. These bindings do regular stepping through history and prefix search. They allow resh to record bindings usage metadata. * Enabled by default in zsh * Disabled by default in bash Enable/disable for THIS shell session $ reshctl enable arrow_key_bindings $ reshctl disable arrow_key_bindings Enable/disable for FUTURE shell sessions $ reshctl enable arrow_key_bindings_global $ reshctl disable arrow_key_bindings_global See what your current setting is $ reshctl status COMPLETIONS Zsh and bash completions for 'reshctl' command were installed and should be working. CHECK FOR UPDATES $ reshctl update GRAPHS You can get some graphs of your history by running $ ISSUES Please report issues to: https://github.com/curusarn/resh/issues UNINSTALL You can uninstall resh at any time by running $ rm -rf ~/.resh/ "
