说明
ccze is a robust log colorizer written in C, designed as a drop-in replacement for colorize with better performance and lower resource usage. It reads log data from standard input and outputs colorized text using ncurses, raw ANSI escape codes, or HTML. The tool uses a plugin architecture to recognize and colorize different log formats including syslog, Apache httpd, Postfix, Squid, Exim, fetchmail, procmail, and vsftpd. Each plugin understands the structure of its target log format and applies appropriate colors to timestamps, hostnames, severity levels, and other fields. Output defaults to ncurses mode but the `-A` flag produces raw ANSI output suitable for piping to `less -R` or other tools.
