Synopsis
times
Description
The built-in prints the accumulated user and system times for the shell and its children.
Options
None.
Operands
None.
Standard output
Two lines are printed to the standard output, each in the following format:
1m2.345678s 3m4.567890s
The first field of each line is the user time, and the second field is the system time. The first line shows the times consumed by the shell itself, and the second line shows the times consumed by its child processes.
Errors
It is an error if the times cannot be obtained or the standard output is not writable.
Exit status
Zero unless an error occurred.
Compatibility
The times built-in is defined in POSIX.
POSIX requires each field to be printed with six digits after the decimal point, but many implementations print less. Note that the number of digits does not necessarily indicate the precision of the times.
