asked on Script not executing
Hello,
I have a long mitigation script and upon testing I noticed its not mitigation the target file I have it for any help would be great and I can take out the portion I am dealing with and run it by itself. It is an if statment and its a mystery to me. It is the part that is going to insert the sulogin string to /etc/inittab.
