'''info commands''' ''?pattern?''

If ''pattern'' isn't specified, returns a list of names of all the Tcl commands in the current namespace, including both the built-in commands written in C and the command procedures defined using the [proc] command. If ''pattern'' is specified, only those names matching ''pattern'' are returned. Matching is determined using the same rules as for [string match]. ''Pattern'' can be a qualified name like Foo::print*. That is, it may specify a particular [namespace] using a sequence of namespace names separated by ::s, and may have pattern matching special characters at the end to specify a set of commands in that namespace. If ''pattern'' is a qualified name, the resulting list of command names has each one qualified with the name of the specified namespace.

''[MGS] [[2004/03/14]]'' - Don't forget that '''info commands''' will not tell you the names of all possible commands - some commands are auto-loaded using the [unknown] and [auto_load] mechanism. To get a list of all possible commands, I use something like this:

 proc commands {pattern} {
   return [lsort -unique [concat \
     [info commands $pattern] \
     [array names ::auto_index $pattern] \
   ]]
 }
