What command provides a static summary of CPU filesystem and partition statistics since the system booted?

The command that provides a static summary of CPU filesystem and partition statistics since the system booted is "iostat". This command is part of the sysstat package and is specifically designed to monitor system input/output device loading by observing the time the devices are active in relation to their average transfer rates.

When you run "iostat" without any options, it shows CPU statistics along with input/output statistics for each partition. This information includes how much CPU time is spent on user processes, system processes, idle processes, as well as details about read and write operations on storage devices since the last reboot. This makes it a useful tool for system administrators to assess the performance and throughput of the server's disks and CPUs.

The other commands do not serve this specific purpose. "cpuinfo" typically displays detailed information about the CPU architecture. "top" provides a dynamic, real-time view of system processes and resource usage but does not summarize the statistics since the last boot. "vmstat" focuses on virtual memory statistics, not providing a comprehensive overview of filesystem and partition statistics.
