banner

From Mac Guides

banner is almost an entirely useless Terminal program used to render text in a very, very large font, composed of the ASCII character "#". Presumably, the output is useful for printing on old-style printer paper

Examples

First, make sure your terminal window is pretty wide (132 columns)

To print out "Hello" in a really big way:

 banner Hello!

To print out "MacRumors" and send the result to TextEdit

 banner MacRumors.com | open -f -e

To print "Space Ghost" in 80 columns

 banner -w 80 "Space Ghost"

To print a banner and save the results in a file on the desktop

 banner "Happy Birthday" > ~/Desktop/birthdaybanner.txt

Man Page Excerpt

Banner prints a large, high quality banner on the standard output. If the message is omitted, it prompts for and reads one line of its standard input. The output should be printed on paper of the appropriate width, with no breaks between the pages.
