'''file extension''' ''name'' Returns all of the characters in ''name'' after and including the last dot in the last element of ''name''. If there is no dot in the last element of ''name'' then returns the empty string. ---- [AMG]: http://www.fileinfo.net/ can be used to make sense of many common and uncommon file extensions. Its entry for .tcl [http://www.fileinfo.net/extension/tcl] is rather curious: ''Script written in the Tool Command Language (pronounced "tickle"), a simple textual language used for sending commands to text editors, debuggers, and shells'' So... how does Tcl send commands to text editors, debuggers, and shells? ---- See also: * [file] * [file rootname] * [file tail] ---- !!!!!!
