get configuration setting for maximum CPU frequency:

vcgencmd get_config arm_freq

get actual current CPU frequency (will vary based on processing load):

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

Maximum CPU frequency:

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq

Minimum CPU frequency:

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq

Current CPU frequency (will vary based on processing load):

cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq

get CPU temperature:
