как можно в history посмотреть время введения команды? Или это править надо?

man bash
/HISTTIMEFORMAT

Pattern not found (press RETURN)

HISTSIZE
              The number of commands to remember in the command  history  (see
              HISTORY below).  The default value is 500.
       HISTTIMEFORMAT
              If  this  variable  is  set and not null, its value is used as a
              format string for strftime(3) to print the time stamp associated
              with  each  history  entry displayed by the history builtin.  If
              this variable is set, time stamps are  written  to  the  history
              file so they may be preserved across shell sessions.
       HOME   The home directory of the current user; the default argument for
              the cd builtin command.  The value of this variable is also used
              when performing tilde expansion.
