@gniourf_gniourf there is no need to use quotes for the argument of unset.

@jarno: these quotes MUST be used: if you have a file named array0 in the current directory, then since array[0] is glob, it will first be expanded to array0 before the unset command.

@gniourf_gniourf you are correct. This should be corrected in Bash Reference Manual that currently says "unset name[subscript] destroys the array element at index subscript".
