Question

Which of the following commands does not update the modification timestamp of /tmp/myfile.txt?

A file /tmp/myfile.txt
B echo "Hello" >/tmp/myfile.txt
C sed -ie "s/1/2/" /tmp/myfile.txt
D echo -n "Hello" >>/tmp/myfile.txt
E touch /tmp/myfile.txt

Explanation

The file utility reads a file to identify its type and does not alter the file or its timestamps. Writing, editing in place, appending data, and using touch can update the modification timestamp.
