cpufreq-aperf:tldr:ec3ea
The command "sudo cpufreq-aperf -c ${1}" can be broken down as follows:
-
"sudo" is a command that stands for "superuser do" and is used to run a command with administrative privileges. It allows users to perform tasks as the root user or another user.
-
"cpufreq-aperf" is a command-line tool used to measure the processor's frequency and performance on Linux systems.
-
"-c" is an option or flag that is used to specify the processor or CPU core for which the frequency and performance will be measured.
-
"${1}" is a placeholder for an argument that should be provided when executing the command. In this case, it is used to specify the CPU core number. The value of ${1} will be replaced with the actual CPU core number when running the command. For example, if you want to measure the frequency and performance of CPU core 1, you would execute the command as "sudo cpufreq-aperf -c 1".
