[Bug 913292] Re: 'time' ignores arguments (such as '-f') and discards them as commands

[Dave Gilbert]

You've fallen into an old-trap; bash (and many other shells) have 'time' builtins, and it's that time that you are running
rather than the one from coreutils ; if you replace your command with  /usr/bin/time rather than just time it works.

To see the syntax of the time builtin, if you are in bash do    help
time.

** Changed in: coreutils (Ubuntu)

Title:
  'time' ignores arguments (such as '-f') and discards them as commands

Status in “coreutils” package in Ubuntu:
  Invalid

Bug description:
  As defined in the manpage of 'time' (see
  http://manpages.ubuntu.com/manpages/natty/man1/time.1.html), the
  'time' command should understand the following command:

         time -f "%E real,%U user,%S sys" ls -Fs

  However, it seems to ignore the '-f' argument:

         $  time -f "%E real,%U user,%S sys" ls -Fs
         -f: command not found

         real	0m3.423s
         user	0m0.232s
         sys	0m0.188s

  That could be considered undefined behaviour, for example, when shell
  scripts depend on the '-f' flag (or other flags, for that matter).
