Uplny seznam toho, co znam je:
 
stty sane . . . opravi nastaveni terminaloveho zarizeni
  na nejake rozumne defaultni hodnoty
 
reset . . . udela neco z toho, co stty sane (nebo mozna vsechno)
  a navic do terminalu posle inicializacni stringy, co najde
  v terminfo (jsou tam tri, is1-3, ale mozna posle jen neco)
 
echo -en '\033c' . . . na konzoli navic provede nizkourovnovy
  reset v kernelu, ktery muze spravit i veci, ktere stty ani reset
  neopravi (ta sekvence by asi spravne mela byt v terminfo ve vyse
  zminenych is1-3, ale pokud vim, tak tam neni)

Zkuste si strace na tyto prikazy a zjistite to uplne presne.

tput init nebo tput reset
 
man tput
 
       init   If the terminfo database is present and an entry for the
user's
terminal exists (see -Ttype, above),
              the following will occur: (1) if present, the terminal's
initialization strings will be output (is1,
              is2, is3, if, iprog), (2) any delays (e.g., newline) specified
in the entry will be set in  the  tty
              driver, (3) tabs expansion will be turned on or off according
to
the specification in the entry, and
              (4) if tabs are not expanded, standard tabs will be set (every
8
spaces).  If an entry does not con<AD>
              tain  the  information  needed  for any of the four above
activities, that activity will silently be
              skipped.
 
       reset  Instead of putting out initialization strings, the terminal's
reset strings will be output  if  pre<AD>
              sent (rs1, rs2, rs3, rf).  If the reset strings are not
present,
but initialization strings are, the
              initialization strings will be output.  Otherwise, reset acts
identically to init.
