Full Discussion: small sed script on command line.

small sed script on command line.
Can anyone help me get this small sed script to work in shell on the command line?
I need it in a one liner really as i want to edit many scripts in a for loop and dont want to have to invoke a separate script each time.

Code:
 #!/bin/sh 

sed '/mailx\ -s.*$ { 
i\ 
#Comment above mailx line 
c\ 
mailx -s "blahblah blah my new subject" $someone_who_cares 
}' $1

The script needs to match a pattern, insert a line above it and then change the pattern to something else.

I've tried the following and no joy

Code:
sed '/mailx\ -s.*$/ { i\ #Comment above mailx line c\ mailx -s "blahblah blah my new subject" $someone_who_cares }' file > file2  

sed '/mailx\ -s.*$/ {; i\; #Comment above mailx line ;c\; mailx -s "blahblah blah my new subject" $someone_who_cares ;};' file > file2
