pidstat:tldr:6980b
The command "pidstat ${2} ${10}" is used to collect and display statistics for a specified process or processes.
Here's the breakdown of each part of the command:
-
"pidstat": This is the actual command. It is used to monitor and report various statistics related to process activity on a system.
-
"${2}": This is a placeholder that represents the second argument or parameter given after executing the command. The symbol "${ }" is often used in shell scripts to refer to command-line arguments or variables. For example, if you run the command "pidstat 1234 5", then "${2}" would be replaced with "1234".
-
"${10}": Similarly, this placeholder represents the tenth argument or parameter given after executing the command. So if the command is executed with ten arguments like "pidstat arg1 arg2 ... arg10", then "${10}" will be replaced with the value of "arg10".
Overall, the command "pidstat ${2} ${10}" would run the "pidstat" command and display statistics for the process specified as the second argument and for a duration specified by the tenth argument.
