Table 14-1 summarizes the namespace operations:

Table 14-1. The `namespace` command.
`namespace current`	Returns the current namespace.
`namespace children ?name? ?pat?`	Returns names of nested namespaces. `name` defaults to current namespace. `pat` is a `string match` pattern that limits what is returned.
`namespace code` `script`	Generates a `namespace inscope` command that will eval `script` in the current namespace.
`namespace delete` `name` `?name? ...`	Deletes the variables and commands from the specified namespaces.
`namespace eval` `name cmd` `?args? ...`	Concatenates `args`, if present, onto `cmd` and evaluates it in `name` namespace.
`namespace export ?-clear? ?pat? ?pat? ...`	Adds patterns to the export list for current namespace. Returns export list if no patterns.
`namespace forget` `pat` `?pat? ...`	Undoes the `import` of names matching patterns.
`namespace import ?-force?` `pat` `?pat? ...`	Adds the names matching the patterns to the current namespace.
`namespace inscope` `name cmd` `?args? ...`	Appends `args`, if present, onto `cmd` as list elements and evaluates it in `name` namespace.
`namespace origin` `cmd`	Returns the original name of `cmd`.
`namespace parent ?name?`	Returns the parent namespace of `name`, or of the current namespace.
`namespace qualifiers` `name`	Returns the part of `name` up to the last `::` in it.
`namespace which ?flag?` `name`	Returns the fully qualified version of `name`. The `flag` is one of `-command`, `-variable`, or `-namespace`.
`namespace tail` `name`	Returns the last component of `name`.
