What's the deal with the banner command?
In some versions of UNIX and Linux there\'s a banner command (usually /usr/bin/banner) that prints great output like this:
##### ####### # ##### #

If anyone is interested, here's a Java version. It generates a String, and it's up to you whether you use System.out.println() or your Logging framework of choice.
public class Banner { public static String print(String s, char stdCh) { StringBuilder sb = new StringBuilder(); for (int row = 0; row < 8; row++) { sb.append('\n'); for (char ch : s.toCharArray()) { int enc = CHAR_LIST.indexOf(ch); if (enc < 0) continue; for (int col = 0; col < 8; col++) { sb.append(isPresent(row, enc, col) ? charToPrint(ch, stdCh) : ' '); } } } return sb.append('\n').toString(); } private static char charToPrint(char ch, char stdCh) { return ch != ' ' && stdCh != 0 ? stdCh : ch;
