Problem? s bash-om

[Jachcemjest]

Nazdar!
Potrebujem dat jednemu programu ako parameter retazec

.,#-%+$,-!./+""**)-')+-/"#*/(%%

-na konci je medzera (za tymi dvoma percentami)

Ja ze bez problemu, vyeskejpujem znaky interpretovane v "", co su podla 'man bash' $, \, `.

Na moje prekvapenie z neho vypadli taketo divne hlasky, a retazec vypisal jedine ked som "vyeskejpoval" aj vykricnik, ale potom vypisal aj backslash pred tym vykricnikom....

petko@jachcemjest ~/Projects/smbconf $  echo ".,#-%+\$,-!./+\"\"**)-\')+-/\"#*/(%% "
bash: !./+\"\"**: event not found
petko@jachcemjest ~/Projects/smbconf $  echo ".,#-%+\$,-\!./+\"\"**)-\')+-/\"#*/(%% "
.,#-%+$,-\!./+""**)-\')+-/"#*/(%%
petko@jachcemjest ~/Projects/smbconf $  echo ".,#-%+\$,-!\./+\"\"**)-\')+-/\"#*/(%% "
bash: !\./+\"\"**: event not found

Neviete niekto o co ide?

null ~ # echo ".,#-%+\$,-\!./+\"\"**)-\')+-/\"#*/(%% "
.,#-%+$,-\!./+""**)-\')+-/"#*/(%%
null ~ #

[Jachcemjest]

null ~ # echo ".,#-%+\$,-\!./+\"\"**)-\')+-/\"#*/(%% "
.,#-%+$,-\!./+""**)-\')+-/"#*/(%%
null ~ #

No ako som pisal, to som skusal, problem je, ze ked vyeskejpujem aj ten vykriznik, tak to tam vypise aj ten backslash, ktory tam nechcem...

A samozrejme, rad by som aj vedel, ze preco to robi, to co to robi

fox@bacchus ~ $ echo ".,#-%+\$,-"\!"./+\"\"**)-\')+-/\"#*/(%% "

vykricnik je 'klicovy slovo' a expanduje se jako prvni ...

 Event Designators
       An event designator is a reference to a command line entry in the history list.

       !      Start a history substitution, except when followed by a blank, newline, carriage return, = or ( (when the extglob shell option is enabled using the shopt builtin).
       !n     Refer to command line n.
       !-n    Refer to the current command line minus n.
       !!     Refer to the previous command.  This is a synonym for `!-1'.
       !string
              Refer to the most recent command starting with string.
       !?string[?]
              Refer to the most recent command containing string.  The trailing ? may be omitted if string is followed immediately by a newline.
       ^string1^string2^
              Quick substitution.  Repeat the last command, replacing string1 with string2.  Equivalent to ``!!:s/string1/string2/'' (see Modifiers below).
       !#     The entire command line typed so far.

Hm... diky...
To by ma ani nenapadlo, ze sa moze nieco robit so stringom v uvodzovkach pred tym, ako sa "spracuje" ten string....
