time keyword in
zsh produces output in the format specified by the variable
The default value of this variable is
%J %U user %S system %P cpu %*E total
You can change this like this, for example:
TIMEFMT=$'%J\n%U user\n%S system\n%P cpu\n%*E total'
(this really just inserts a few newline characters into the default format string)
Which gives the following kind of output:
$ time sleep 2
Or, somewhat closer to what
$ time sleep 2
See the documentation for the
TIMEFMT variable in the
On my system (running zsh 5.7.1), this reads
The format of process time reports with the time keyword. The
default is `%J %U user %S system %P cpu %*E total'. Recognizes
the following escape sequences, although not all may be
available on all systems, and some that are available may not be
%% A `%'.
%U CPU seconds spent in user mode.
%S CPU seconds spent in kernel mode.
%E Elapsed time in seconds.
%P The CPU percentage, computed as 100*(%U+%S)/%E.
%W Number of times the process was swapped.
%X The average amount in (shared) text space used in
%D The average amount in (unshared) data/stack space used in
%K The total space used (%X+%D) in kilobytes.
%M The maximum memory the process had in use at any time in
%F The number of major page faults (page needed to be
brought from disk).
%R The number of minor page faults.
%I The number of input operations.
%O The number of output operations.
%r The number of socket messages received.
%s The number of socket messages sent.
%k The number of signals received.
%w Number of voluntary context switches (waits).
%c Number of involuntary context switches.
%J The name of this job.
A star may be inserted between the percent sign and flags
printing time (e.g., `%*E'); this causes the time to be printed
in `hh:mm:ss.ttt' format (hours and minutes are only printed if
they are not zero). Alternatively, `m' or `u' may be used
(e.g., `%mE') to produce time output in milliseconds or
