imadev:~$ unset array imadev:~$ array[$(( $( echo -n 1001 ) - 1001 ))]=1 imadev:~$ unset array bash: 1001: command not found And similar... hmm, this is beyond weird. I have no idea what's happening here. But if you want to work around the problem, I would suggest simplifying things. For starters, you do not need $((...)) inside an array index because the [...] already introduce a math context. So: imadev:~$ array[$(echo -n 1001) - 1001]=1 imadev:~$ set | grep array= array=([0]="1") imadev:~$ unset array And that assumes you need to keep the command substitution for some unstated reason. If you can get rid of that too, that would be even better.
