${file%%.txt}

dear Vino,

I am really curious to know the expression ${file%%.txt} .

Please can you explain it to me.
I was looking for a solution to extract the extrension of a file name. I wanted to split a file by line numbers but the unix split command splits the file with suffix is aa, ab, ac etc which I want to convert into 00, 01 etc and I was struggling to get the extension part.

Thanks a lot in anticipation.

NAME
textutil::split - Procedures to split texts SYNOPSIS
package require Tcl 8.2 package require textutil::split ?0.7? ::textutil::split::splitn string ?len? ::textutil::split::splitx string ?regexp? _________________________________________________________________ DESCRIPTION
The package textutil::split provides commands that split strings by size and arbitrary regular expressions. The complete set of procedures is described below. ::textutil::split::splitn string ?len? This command splits the given string into chunks of len characters and returns a list containing these chunks. The argument len defaults to 1 if none is specified. A negative length is not allowed and will cause the command to throw an error. Providing an empty string as input is allowed, the command will then return an empty list. If the length of the string is not an entire multiple of the chunk length, then the last chunk in the generated list will be shorter than len. ::textutil::split::splitx string ?regexp? This command splits the string and return a list. The string is split according to the regular expression regexp instead of a simple list of chars. Note that if you parentheses are added into the regexp, the parentheses part of separator will be added into the result list as additional element. If the string is empty the result is the empty list, like for split. If regexp is empty the string is split at every character, like split does. The regular expression regexp defaults to "[\t \r\n]+". BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category textutil of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. SEE ALSO
