Answer by Gilles Quénot for Print array elements on separate lines in Bash?

Try doing this :

$ printf '%s\n'"${my_array[@]}"

The difference between $@ and $*:

• Unquoted, the results are unspecified. In Bash, both expand to separate argsand then wordsplit and globbed.

• Quoted, "$@" expands each element as a separate argument, while "$*"expands to the args merged into one argument: "$1c$2c..." (where c isthe first char of IFS).

You almost always want "$@". Same goes for "${arr[@]}".

Always double quote them!
