Tcl also supports commands to change and display the current working
directory.

These are:

   `cd ?dirName?`:   Changes the current directory to `dirName` (if `dirName` is given, or to the `$HOME` directory if `dirName` is not given. If `dirName` is a tilde (`~`), `cd` changes the working directory to the user's home directory.  If `dirName` starts with a tilde, then the rest of the characters are treated as a login ID, and `cd` changes the working directory to that user's $HOME.

   `pwd`:   Returns the current directory.

***Example***

======
set dirs [list TEMPDIR]

puts "[format "%-15s  %-20s " "FILE" "DIRECTORY"]"

foreach dir $dirs {
    catch {cd $dir}
    set c_files [glob -nocomplain c*]

    foreach name $c_files {
        puts "[format "%-15s  %-20s " $name [pwd]]"
    }
}
