pwd

pwd(3tcl)						       Tcl Built-In Commands							 pwd(3tcl)

__________________________________________________________________________________________________________________________________________________

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 minimizes  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

KEYWORDS
