Note: This is a assuming I already have a user named "unique" in my smb.conf line.

#####This is the part I have issues with:
## function to add user to the Samba config and restart daemon
createNewSambaAllow(){
# Copy to backup the config:
cp /etc/samba/smb.conf /etc/samba/smb.conf-$_now
# stuff the line we need to append to into a variable called $oldline
# this is supposed to look like this "valid users = unique thing1 thing2 thing3 alice"
oldline = grep unique /etc/samba/smb.conf
# delete the old line in the smb.conf
sed '/unique/d' /etc/samba/smb.conf
