Had a recent test at work and of course missed the pass mark by 1 question, Im good like that. Anyway when I think back there's only one question I felt pretty unsure of:
What does the command !?abc?* do?
1. Nothing, this is invalid syntax
2. Appends * to the most recent command containing the symbols !?
3. Appends * to the most recent command containing the string abc
4. Searches for all files with abc in their heading
There is of course only one correct answer. I went for number 1, anyone able to shed light if I was correct or not?
