time: Setting Format

 
 1.1 Setting the Output Format
 =============================
 
 'time' uses a "format string" to determine which information to display
 about the resources used by the command it runs.  ⇒Format String,
 for the interpretation of the format string contents.
 
    You can specify a format string with the command line options listed
 below.  If no format is specified on the command line, but the 'TIME'
 environment variable is set, its value is used as the format string.
 Otherwise, the default format built into 'time' is used:
 
      %Uuser %Ssystem %Eelapsed %PCPU (%Xtext+%Ddata %Mmax)k
      %Iinputs+%Ooutputs (%Fmajor+%Rminor)pagefaults %Wswaps
 
    The command line options to set the format are:
 
 '-f FORMAT'
 '--format=FORMAT'
      Use FORMAT as the format string.
 
 '-p'
 '--portability'
      Use the following format string:
 
           real %e
           user %U
           sys %S
 
      The default output format of time differs widely between
      implementations.  This option (in its short form -p) is supported
      by all POSIX-compliant 'time' implementations to retrieve basic
      information in the described format.
 
 '-v'
 '--verbose'
      Use the built-in verbose format, which displays each available
      piece of information on the program's resource use on its own line,
      with an English description of its meaning.
