grc is a generic colouriser written in Python that inserts ANSI colour codes into the output of commands and log files to make them more readable. It provides two programs: grcat, a filter that colourises standard input based on regexp configuration files, and grc, a wrapper that runs commands with appropriate colour configurations.

Use cases

• colorize command output like ping, netstat, ps, tail
• make log files easier to read with colors
• filter and highlight text based on regular expressions
• replace multiple single-purpose colorizers like colortail and ccze
• colorize traceroute and syslog output

When to choose

• you want a single configurable tool to colorize arbitrary command output
• you prefer regexp-based colouring rules you can customize per command
• you work heavily in the terminal with logs and long command output

When to avoid

• you need structured log parsing or JSON log processing rather than visual colouring
• you want automatic colouring without writing or maintaining configuration files
• you need a GUI or non-terminal text processing tool
