The command "sar -q ${1}" is a Unix command that is used to check the system's load average and CPU utilization.
Here's a breakdown of the command:
-
"sar" is a system monitoring command in Unix-like operating systems, standing for "System Activity Reporter". It provides information about various system resources such as CPU, memory, disk usage, network statistics, etc. In this case, it is used to monitor the system's load average and CPU utilization.
-
"-q" is an option or argument passed to the "sar" command. It specifies that we want to retrieve the system's load average and CPU utilization statistics.
-
"${1}" is a placeholder or variable that represents the first command-line argument passed to the script or command. In Unix-like systems, command-line arguments are represented using positional parameters. The variable "${1}" represents the first parameter passed to the script or command, and in this case, it is used to provide additional information or specify the specific usage or time range for retrieving the load average and CPU utilization.
So, when you execute the command "sar -q ${1}", it will retrieve and display the system's load average and CPU utilization statistics based on the specified parameters or time range provided as the first command-line argument.
