The problem comes from discovering what the 'last line' is. sed et al can't look back in time to see that. awk can read the file twice however, once to determine, once to substitute:
\014 is the octal for a line feed, \r is its substitute. Use whatever you want for it.

Ok, so I have bunch of files that are named "orange__file_name.asm" and I want to batch rename them to "file_name.asm" I know that using "ls | sed s/orange__//" will get rid of the part of the file name I do not want. But how do I combine that with the mv command to actually do it?

yexpand
YEXPAND(1) General Commands Manual YEXPAND(1)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.
