typeset

The typeset command line tool is used in Unix-like operating systems, particularly in the Bash shell. It is used to define or modify shell variables and their attributes. The typeset command allows you to declare variables, specifying their types like integer, array, or associative array, using specific options. You can also use it to define attributes for variables, such as read-only, integer-only, or exported. By using the -p option, you can display the attributes and values of all variables or specified variables. The typeset command can be used to create and manipulate arrays, including setting array values, appending values, or removing elements. It also supports the creation and manipulation of associative arrays, which are arrays with key-value pairs. You can use the typeset command to declare and enforce integer arithmetic on variables to ensure they only contain integer values. One of its powerful features is the ability to specify the scope of variables, allowing you to create local variables within functions or loops. Overall, the typeset command is a versatile tool that provides control and flexibility in defining and managing shell variables and their attributes in Unix-like systems.
