Using GNU head, print only the first 10 lines of data.csv without changing it.
Start at the beginning.
$ cat data.csv
The file has 50,000 rows.
How do you preview its first 10 lines?
Fixed. By hand.
head -n 10 data.csvhead prints the beginning of its input. The explicit -n 10 makes the requested count clear; 10 is also the normal default.
