How do I check CPU usage and memory in UNIX?

The mpstat command provides information about CPU performance and utilization by giving CPU statistics for the whole system and each available processor. Running the mpstat command on a Linux system will display an output like the one shown in figure 2.

How do I check storage space in Unix?

That command is df -H. The -H switch is for human-readable format. The output of df -H will report how much space is used, available, percentage used, and the mount point of every disk attached to your system (Figure 1).

How See DNS cache Linux?
