How come it works if I copy an paste the entire script to the command line
sed -e is not required if the arguments following the command are valid arguments. But for grins I tried it on the command line it works as a stand alone command in the script file name is not found.
I still think the problem is that the bash script does not know to look in the directory that it is excuted from. In fact the all the files are in the working directory from when I executed the script line by line.
Lets focus on the problem and not the code in the script.
so if I'm only using a bash shell then this is not required?
If I copy all the lines in the script and paste on the bash command line it works. Is the syntax requirement for a script not the same as line by line commands?

what is the default standard output in a bash shell?
result on screen
blah blah
result on screen
blank screen
in ksh and others the result is directed to the stdout (the Screen)

using either wordpad or notepad as a script editor
simple source file "A"
Apple
Pear
Orange
Grape
original code
result
$ ./trans_xy
Process fruit
touch: cannot touch `Apple\r': No such file or directory
Apple
SOLUTION
result
$ ./trans_xy
Process fruit
file "Apple"
Apple
my suspicion is that Windows 7 has extra hidden garbage "\r" at the end of every line, whats weird is that if I copy and paste the entire script to the command line it works as intended?
