mpstat:tldr:96dcc
The command "mpstat ${2}" is a shell command that uses the "mpstat" utility program. The ${2} is a variable that represents the second argument passed to the script or command.
The "mpstat" utility is used to monitor and report processor related statistics on Unix-like systems. It provides information about CPU utilization, individual CPU utilization, interrupts, and more.
By using ${2}, the command is likely designed to take a specific input or parameter as the second argument when executing the script or command.
For example, if you run a shell script like "script.sh" and execute it as "bash script.sh parameter1 parameter2", then ${2} would represent "parameter2" in this case.
So, the command "mpstat ${2}" would run the "mpstat" program with the value of the second argument provided when running the script or command.
