For example, the command x/.*\n/g/foo/p will print all lines which contain the string “foo†— x will first

You can think of regular expressions as wildcards on steroids. You are probably familiar with wildcard notations such as *.txt to find all text files in a file manager. The regex equivalent is ^.*\.txt$. But you
