Hello all. This is a rookie's question.
 I am trying to a simple text regular expression replacement.
The text goes as follows (white spaces may change:
tcl_cmd bla > kuku
I want to change it to:
tcl_cmd bla > kuku.rev1
When trying to use replace-regexp \(>[ ]+[^ ]+\)  to \1.rev1 I get:
tcl_cmd bla > kuku
.rev1
This is quiet different than using the \W+ with perl...
I think that emacs matches within [^ ]+ \n too. Trying to use [^ \n]+ did
not solve the issue either.
Any thoughts?

With replace-regexp you need to type C-q C-j instead of \n to match a
newline.  (Emacs 22.1 gives you a hint to that effect when you type
`\n' in the regexp.)

You could do it (almost) the same way you'd do it in perl:

'\(> +\w+\)'  to '\1.rev1'

You can also use '$' to explicitly signal the end of line, which is
helpful if you have other incidences of '> ' that occur earlier in the
line:

'\(> +\w+\)$'  to '\1.rev1'

HTH,

Tyler
