set prompt = pwd
Assume that you want to set your prompt to display the current working directory followed by a percent symbol and then a space. The command pwd can be used to display this information, so explain why the following command does not have the expected result:
set prompt=" `pwd`'%' "
Its a review question im having trouble on.

pwd
pwd(1T) Tcl Built-In Commands pwd(1T)
__________________________________________________________________________________________________________________________________________________
NAME
pwd - Return the absolute path of the current working directory
SYNOPSIS
pwd
_________________________________________________________________
DESCRIPTION
Returns the absolute path name of the current working directory.
EXAMPLE
Sometimes it is useful to change to a known directory when running some external command using exec, but it is important to keep the appli-
cation usually running in the directory that it was started in (unless the user specifies otherwise) since that minimises user confusion.
The way to do this is to save the current directory while the external command is being run:
set tarFile [file normalize somefile.tar]
set savedDir [pwd]
cd /tmp
exec tar -xf $tarFile
cd $savedDir
