sed can not work in script file in Windows

I once write a simple sed command like this

s/==/EQU/

while I run it in command line:

sed 's/==/EQU' filename

it works well, replace the '==' with 'EQU', but while I write the command to a script file named replace.sed, run it in this way:

sed -f replace.sed filename

there is a error, says that 

sed: file replace.sed line 1: unknwon option to 's'

What I want to ask is that is there any problem with my script file replace.sed while it run in windows?

The unknown option is almost invariably a rogue character after the trailing / (which is missing from your command line version, by the way so it should complain about an unterminated command).

Have a look at you replace.sed again. You may have a funny character at the end, which could include the ' if you forgot to delete it, or even a CTRL-M DOS-style line ending, though CygWin seems to handle this okay - you haven't specified which sed you're using (that may help).

Okay, based on your edit, it looks like one of my scattergun of suggestions was right :-) You had CTRL-M at the end of the line because of the CR/LF line endings:

At the end of each line in the *.sed file, there was a 'CR\LF' pair, and that the problem, but you cannot see it by default, I use notepad to delete them manually and fix the problem. But I have not find a way to delete it automatically or do not contain the 'new-line' style while edit a new text file in windows.

You may want to get your hands on a more powerful editor like Notepad++ or gVim (my favourite) but, in fact, you do have a tool that can get rid of those characters :-) It's called sed.

sed 's/\015//g' replace.sed >replace2.sed

should get rid of all the CR characters from your file and give you a replace2.sed that you can use for your real job.
