percol – interactive grep tool in your terminal

percol is an interactive grep tool in your terminal.

percol receives input lines from stdin or a file, lists up the input lines, waits for your input that filter/select the line(s), and finally outputs the selected line(s) to stdout.

This is free and open source software.

Key Features

  • Efficient: With lazy loads of input lines and query caching, percol handles huge inputs efficiently.
  • Customizable: Through configuration file (rc.py), percol’s behavior including prompts, keymaps, and color schemes can be heavily customizable.
  • Migemo support: By supporting C/Migemo, percol filters Japanese inputs fast.
