redis info 能不能具体到某一项的值

我看 info 只能查看 section 层级的值,具体每一项能一次性输出嘛,比如 latest_fork_usec

redis-cli 的命令不行,但是如果你只想看某一个值,通过 linux 的管道 加上 grep 不是简单么?

# redis-cli -h 127.0.0.1 -p 6379 info | grep latest_fork_usec
latest_fork_usec:87080

想匹配多个,grep 用正则去匹配也可以啊

# redis-cli -h 127.0.0.1 -p 6379 info | grep -E "(latest_fork_usec:|used_memory:)"
used_memory:2198268912
latest_fork_usec:88376
