I have a script that runs sed through a loop. Everything is working
properly except for situations where a username is found with another
name. For example I am looking to change the following -
foo: foo(a)null.com
to
foo: /dev/null
This works properly but the issue is any other name, such as the
ones below will also be changed . So for example
dofoo: dofoo(a)null.com
is changed to
dofoo: do/dev/null
and
pefoo: pefoo(a)null.com
is changed to
pefoo: pe/dev/null.
I need to pass an argument, etc so that on the entry for "foo" is
modified. Any help would be appreciated. Thanks.

dofoo: dofoo(a)null.com
pefoo: pefoo(a)null.com
foo: foo(a)null.com

I don't see how this is going to work. I may need to expand on what I
need to do. The sed command runs in a script with multiple names of
users. The file is runs against is a flat file and the syntax may
start with a comment in the first filed or may not (i.e - ngj or
#foongj). Either way I need a way to get only the specific user I
need modifie - in this case ngj. I tried the above and there was no
modifiction.

Then there's something about your input file you aren't telling us. Look:

$ cat file
foo: foo(a)null.com
#foo: foo(a)null.com
dofoo: dofoo(a)null.com
pefoo: pefoo(a)null.com
$ sed 's#^foo:.*#foo: /dev/null#' file
foo: /dev/null
#foo: foo(a)null.com
dofoo: dofoo(a)null.com
pefoo: pefoo(a)null.com
$ awk '$1=="foo:"{ $2="/dev/null/" }1' file
foo: /dev/null/
#foo: foo(a)null.com
dofoo: dofoo(a)null.com
pefoo: pefoo(a)null.com

If that's not what you want, please provide a clearer description of your
requirements along with some small set of sample input and the expected output
given that input.
