Hi, On Ubuntu 20.04, I installed the latest git master version of bash. Then I check the document for declare built-in command and also check the online document located here: https://www.gnu.org/software/bash/manual/bash#Bash-Builtins.
The online version of the document for declare told the following usage: declare declare [-aAfFgilnrtux] [-p] [name[=value] …] [...] The -p option will display the attributes and values of each name. When -p is used with name arguments, additional options, other than -f and -F, are ignored. But I can't find the same notes from the local version of the document for this command given by `help declare', any hints for this problem? Regards -- Hongyi Zhao <hongyi.z...@gmail.com>
