NAME

       yexpand - tool to expand environment variables in Nypatchy cradles

SYNOPSIS

       yexpand inputfile [ outputfile ]

DESCRIPTION

       yexpand	is  a  very simple script to expand environment variables in a text file to their current values in the shell environment.  It was
       written to be used with nypatchy cradles.  It is recommended you not try to use it for any other purposes (note BUGS below).

USAGE

       yexpand takes inputfile as input, replaces all instances of shell variables (in the form $VARIABLE or ${VARIABLE}) with their current  val-
       ues  in the environment, and saves the result to outputfile.  Undefined variables are replaced with the empty string.  If outputfile is not
       given, the result is instead saved to the current directory as a file of the same name as inputfile.  Thus an input  file  in  the  current
       directory will be overwritten.

BUGS

       This  script  is  very  simple-minded.  Since it basically just echos its input file as a here-doc, it will attempt to perform all types of
       shell substitution (command substitution, etc.) as well as variable substitution.  Hence it is likely to fail on anything except  the  very
       simplest text files.

       Additionally, this script creates a temporary file.  The file is created in the current directory, so there should not be security implica-
       tions.  However, any existing file named file.yexp (where file is the basename of inputfile) in the current directory will  be  overwritten
       and then deleted.
