I am not a Linux expert. But in dos I can execute more than one command at an conce using the pipe simbol.
See the following command line: dir > out.txt | notepad out.txt This will execute dir, output to a text file and the open the file using notepad. The malicious hacker may use: command01 | command02 I think Linux also has this feature. Am I right or wrong????
