Передача параметров в Bash

Special Parameters
  The shell treats several parameters specially.  These parameters may only be referenced; 
  assignment to them is not allowed.
  *      Expands to the positional parameters, starting from one.  When the expansion is not 
         within double quotes, each positional parameter  expands to  a separate word.  
         In contexts where it is performed, those words are subject to further word splitting 
         and pathname expansion.  When the expansion occurs within double quotes, it expands
         to a single word with the value of each parameter separated by the first character of
         the IFS  special variable.  That is, "$*" is equivalent to "$1c$2c...", where c is the 
         first character of the value of the IFS variable.  If IFS is unset, the parameters are 
         separated by spaces.  If IFS is null, the parameters are joined without intervening 
         separators.
  @      Expands to the positional parameters, starting from one.  When the expansion occurs 
         within double quotes, each parameter expands to a  separate  word.   That  is, "$@" is 
         equivalent to "$1" "$2" ...
