How to output the first line from every file in Linux?

To output the first line from every file in Linux, you can use the head command in combination with a file globbing pattern. Here's the command:

1

head -n 1 *

Explanation:

• head is a command used to print the first lines of a file.
• The option -n 1 specifies that we only want the first line.
• The asterisk * is a file globbing pattern that matches all files in the current directory.

When you run this command, it will display the first line of every file in the current directory.
