difference between $@ and $* in bash script [duplicate]

Answer 1

Difference between $* and $@ is::

"$*" All the positional parameters (as a single word) *

"$@" All the positional parameters (as separate strings)

If you pass three command-line arguments given to a bash script to a C program using ./my_c $@,

you get the result ARG[1] == "par1" ARG[2] == "par2" ARG[3] == "par3"

If you pass three command-line arguments given to a bash script to a C program using ./my_c $*,

you get the result ARG[1] == "par1 par2 par3"
