1 1.3 Redirecting Output
1 ======================
1 
1 By default, 'time' writes the resource use statistics to the standard
1 error stream.  The options below make it write the statistics to a file
1 instead.  Doing this can be useful if the program you're running writes
1 to the standard error or you're running 'time' noninteractively or in
1 the background.
1 
1 '-o FILE'
1 '--output=FILE'
1      Write the resource use statistics to FILE.  By default, this
1      _overwrites_ the file, destroying the file's previous contents.
1 
1 '-a'
1 '--append'
1      _Append_ the resource use information to the output file instead of
1      overwriting it.  This option is only useful with the '-o' or
1      '--output' option.
