Description
Tool that runs programs and summarizes the system resources they use.
The time' command runs another program, then displays information about the resources used by that program, collected by the system while the program was running. You can select which information is reported and the format in which it is shown, or have time' save the information in a file instead of displaying it on the screen.
The resources that time' can report on fall into the general categories of time, memory, and I/O and IPC calls. Some systems do not provide much information about program resource use; time' reports unavailable information as zero values.
