Can't get sed to replace string with semicolon.

I am writing a bash script. In the file /etc/samba/smb.conf, I wish to substitute the string:

 

;       realm = MY_REALM

 

with the string:

 

        realm = GROUP.COM

 

notice the semicolon is gone.

 

SED sees the semicolon as special, and I don't know AWK. Anyone got a one liner:

 

Thanks again to all who respond to my questions regularly,

 

 

To describe my problem in fuller detail as suggested, the command:

 

sed -i 's/";       realm = MY_REALM"/"        realm = GROUP.COM"/g' /etc/samba/smb.conf

 

has issues with the semicolon.

>>> has issues with the semicolon.

 

Maybe, but not in this example. And a semicolon may be special for a shell, but it looks like it is already escaped so that the shell should leave it alone. The quoting you use, asks sed to look for a double quoted string to be replaced by another double quoted string. I don't think you have such quoted strings in the file. So
 
sed -i 's/;       realm = MY_REALM/        realm = GROUP.COM/g' /etc/samba/smb.conf
 
should do.

As Steven said, you have issues with whitespace, not semicolon.
