Skip duplicate history entries in zsh

In zsh, pressing UP searches through the history and brings up all matching commands, even if they are duplicates. That means, sometimes you need to press UP many times to actually find a previous match.

However, it is possible to disable this behaviour and skip duplicate entries from the history. To do that, add one line to your ~/.zshrc:

pgcli — a great alternative to psql

Ever wished for a feature-rich, intuitive command-line postgresql client? Look no further! Presenting, pgcli — a result of pouring creativity into features rather than the name of the tool.


  • Smart autocompletion for almost anything. Even column names in the select query are properly autocompleted from the table you are selecting from;
  • Multi-line query editing support;
  • SQL Syntax highlighting;
  • CLI parameters compatible with psql params. No need to relearn anything;
  • Vi mode, allowing to edit multi-line queries using some of the vi bindings. There are also Emacs bindings too;
  • Installation as easy as pip install pgcli (and if that fails, fix is as easy as xcode-select --install (usually));
