function::task_stime - Linux
Overview
task_stime measures how long a process has spent in user mode. This includes the time spent in the process’s user-mode kernel helper threads. Therefore, this value is equivalent to the "utime" value reported by the getrusage or time calls, plus the time spent in the kernel helper threads.
Syntax
task_stime [PID]
Options/Flags
None
Examples
Example 1: Display the amount of time the current process has spent in user mode
task_stime $$
Example 2: Display the user mode time for a specific process
task_stime 1234
Common Issues
Error: task_stime: No such process
This error occurs when you try to measure the user mode time of a process that does not exist. Ensure that the PID provided is valid.
Integration
Combine with ps
Combine task_stime with ps to display the user mode time for a list of running processes:
ps -e -o pid,user,comm,task_stime
