I am using terminal with MacOSX.

I read this entry introducing about unix array. I tried to access an array as its way, but failed:

a=(1,2) && echo "${a[0]}"

this is the output:


What I expected is 1.

What should I do?


a=('1' '2') && echo "${a[0]}" would be better like this.

In your version you only created a one element array which contains the value "1,2".

    The quotes aren't necessary, just the whitespace (not a comma) to create two items instead of one. – chepner Sep 25 '15 at 13:42
