Help with sed

I need some help. I am working with a bunch of little scripts where I need to change directories. I tried to use sed:

sed -n s/user1/user2/p script

The problem is that that it will only change some of the instances in the file. I'm sure that it is bacause ther are no spaces; but thats whats strange it picks some of the embedded item out but not others.

Guess what I am asking is there a way to change:

/mkdir/homes/usr1 to /mkdir/homes/usr2 in a script?

Thanks a bunch

try sed 's/usr1/usr2/g' filename
The g option specifies global so if you have 2 instances in the same line like:
/home/foo/usr1 /home/bar/usr1
then it will change them to:
/home/foo/usr2 /home/bar/usr2

Hope that Helps
