Bash: text processing and scripts

Final test: Bash: text processing and scripts

Question 4 of 18

One correct answer

app.conf has two lines: `listen=8080` and `# old listen=8080`. What will `sed '/^listen=/s/8080/9090/' app.conf` print?

listen=9090 and # old listen=8080
listen=9090 and # old listen=9090
Nothing — with an address sed prints nothing.
One line, listen=9090 — sed skips the comment.
