There's no reason a shell that provides some other way (than unset) from removing the export attribute cannot allow that other mechanism to remove "export" from a readonly variable (all of that is beyond the standard however - but the standard must not prohibit any of this.)</blockquote>Indeed, this is already possible in bash 5.2.26 (including POSIX mode), ksh93u+ 2012-08-01, yash 2.54 (except POSIXly-correct mode), and zsh 5.9 (native mode):<pre>readonly foo export foo if [ "$YASH_VERSION" ] then typeset -X foo else typeset +x foo fi</pre> Issue History Date Modified Username Field Change ====================================================================== 2024-02-02 22:53 calestyo New Issue 2024-02-02 22:53 calestyo Name => Christoph Anton Mitterer 2024-02-02 22:53 calestyo Section => Shell Command Language 2024-02-02 22:53 calestyo Page Number => 2571 2024-02-02 22:53 calestyo Line Number => 83916, ff. 2024-02-03 00:30 larryv Note Added: 0006647 2024-02-13 20:10 mirabilos Note Added: 0006653 2024-02-13 20:25 mirabilos Note Added: 0006654 2024-02-13 22:48 calestyo Note Added: 0006655 2024-02-13 22:55 calestyo Note Added: 0006656 2024-02-25 07:34 kre Note Added: 0006679 2024-02-25 21:50 calestyo Note Added: 0006680 2024-02-25 22:36 larryv Note Added: 0006681 2024-02-25 23:00 calestyo Note Added: 0006682 2024-02-25 23:16 larryv Note Added: 0006683 2024-02-25 23:22 larryv Note Added: 0006684 ======================================================================
