If I want to replace the string "12345" (in the file test.c) with "54321", how
to make it with shell script or in vi?
thanks,

What's the effect of ^m?
Btw, the file contains more than one instance of the string "12345". Still the
same script in vi?
thanks,

It failed.
I opened test.c with vi (vi test.c), and type ":s/12345/54321/g^m", right?

still the error: Substitute pattern match failed.
But I can confirm the string's existence by using "/12345" to find it.
Another finding is: when i move the cursor to the beginning of string 12345,
and type the above command, it can be replaced. But even in this case, it
can't be replaced globally. only change one instance. :(

Thanks, it works finally.
A minor correction: there shouldn't be space character between % and s.
So my working command is ":%s/12345/54321/g".
Thanks again.
