Hi Charles,

Tcl has a library of "common" functions and utilities known as "tcllib". While it's not part of the "core" of tcl, it's readily available and easy to load and use. Among (many) other things, that library contains a module named "fileutil", which in turn contains "fileutil::find" - which is a Tcl variation of the Unix "find" command.

That said, the Tcl core does contain *many* file (and filesystem) related commands, most of which are collected under the "file" ensemble command. So, check out "file" and its many sub-commands in the standard Tcl man-pages for most of the built-in file support, and take a look at the "fileutil" module of tcllib for other (mostly) higher-level file utilities.


I'm using cygwin with bash console interface (X-windows not installed), mostly for fortran console applications. The cygwin distribution of tcl/tk (tk seems to work even without X-windows!) does not include tcllib, so I got the sourceforge distribution and followed the installation instructions. However, the tutorials I have found do not explain how to load and invoke packages. What is the command syntax to test my tcllib installation by invoking, for example, fileutil::cat under tclsh?

see the man page for package, but it is simply

package require fileutil
fileutil::cat $file

Also, if you look at the docs for fileuitl (or any of the tcllib stuff)
is should show the packlage rquire needed for the commands in the synopsis.

An online locatin of the docs is hosted by activestate here:
