00:00:00,050 --> 00:00:03,000
- [Instructor] Let's have a look at time.txt.

2
00:00:03,000 --> 00:00:06,000
On Mac and Linux we can use the cat command

3
00:00:06,000 --> 00:00:08,080
to show the content of the file.

4
00:00:08,080 --> 00:00:13,050
And now we can do vim plus four is the line number

5
00:00:13,050 --> 00:00:15,050
and D is delete the line,

6
00:00:15,050 --> 00:00:18,080
and then another command for write and quit,

7
00:00:18,080 --> 00:00:21,030
and then time.txt.

8
00:00:21,030 --> 00:00:23,040
And now when we look at time.txt,

9
00:00:23,040 --> 00:00:26,000
we see that the last line is missing.
