How to replace all email addresses in a file set with a shared email address

Question

I have several scripts that have many email addresses in different domains (say domain1.com, domain2.com). I want to replace all of them with a single shared email address in a shared domain, say domain.comleaving a script.

I use below in sed, but it does not work. (It returns the same output as the input, so it looks like the search does not match. However, when I tested the regular expression \S+@\S+/in the online test, it seemed to match the email addresses.)

s/\S+@\S+/[e-mail]/g

For example, I have 2 scripts

$ cat script1.sh
[e-mail]
export SENDFROM="[e-mail]" blah_4

$ cat script2.sh
echo foo|mailx -s "blah" [e-mail],[e-mail],[e-mail]
 [e-mail]
foo [e-mail] bar

My result after sed -ishould be

$ cat script1.sh
[e-mail]
export SENDFROM="[e-mail]" blah_4

$ cat script2.sh
echo foo|mailx -s "blah" [e-mail],[e-mail],[e-mail]
 [e-mail]
foo [e-mail] bar

I use Linux 3.10.0-327.28.2.el7.x86_64

Any suggestion please?

: 's/\S\+@\S\+.com/[e-mail]/g'. search.
