banner command in linux is used to print the ASCII character string in large letter to standrad output.
Example 1: Printing “1234567890” in large letters.
Example 2: Printing “GeeksforGeeks” in large letters. There are two things:
- First, all the letter will be displayed in Capital letters in standard output.
- Second, only “GEEKSFORGE” will be printed as banner has a default capacity of 10 characters in a word. After that, you have to give space which is shown in further examples.
Example 3: Printing “Geeks for Geeks” on display.
Example 4: Trying to print 1234567890123 in a single word but only 1234567890 will be printed on display.
