我运行了 125 个启动服务器的 PHP7.0-FPM，我喜欢在重新启动后检查其状态。使用systemctl status，这当然会产生超过 130 行的输出，很难快速阅读。
root@web2:/etc/php/7.0/fpm/pool.d# systemctl --no-pager --full status php7.0-fpm

我真的不需要CGroup它输出的所有信息。我只想要快速状态和底部的几行日志。我可以像这样过滤输出：
root@web2:/etc/php/7.0/fpm/pool.d# systemctl --no-pager status php7.0-fpm | grep -v "php-fpm: pool www"

但是我失去了 bash 中的彩色格式，而这对于快速状态检查也非常有用。
有没有办法systemctl或类似的命令来获取此状态信息而无需CGroup？
答案1
我认为，如果您以任何方式处理输出，就不可能获得颜色。systemctl检测其输出是否不是 tty 并且不产生彩色输出。这通常是默认行为，因为这通常是您想要的。
作为一种解决方法，这里有一个小脚本，可以解析 CGroup 信息并重新添加颜色：
perl -MTerm::ANSIColor -ne 'next if /^CGroup/ || /├─/;
s/(?>: )active/color("bold green").$&.color("reset")/e; print'
将您的systemctl输出通过该命令，单词active将变成绿色：
systemctl --no-pager status php7.0-fpm |
perl -MTerm::ANSIColor -ne 'next if /^CGroup/ || /├─/;
s/(?>: )active/color("bold green").$&.color("reset")/e; print'
如果您编辑您的问题并添加不同的输出（我没有安装服务，所以我不知道还应该为什么着色），我可以将其扩展到其他可能的输出。
答案2
使用脚本。
例如script --running -c 'systemctl --no-pager status php7.0-fpm' | grep -v "php-fpm: pool www"
