typeset

    typeset [options] [variable[=value ...]]
    typeset -p

In Bash, identical to declare. See declare .

In the Korn shell, assign a type to each variable (along with an optional initial value), or, if no variables are supplied, display all variables of a particular type (as determined by the options). When variables are specified, - option enables the type, and +option disables it. With no variables, - option prints variable names and values; +option prints only the names.

The second form shown is specific to ksh93.
