Question

Which of the following commands replaces every occurrence of bob in the file letter with Bob and writes the output to the file newletter?

A sed '/bob/Bob' letter > newletter
B sed s/bob/Bob/ letter < newletter
C sed 's/bob/Bob' letter > newletter
D sed 's/bob/Bob/g' letter > newletter
E sed 's/bob, Bob/' letter > newletter

Explanation

In sed, s/bob/Bob/g performs a substitution of bob with Bob globally on each line. Redirecting standard output with > newletter saves the transformed content in newletter.
