Reformatting Text Using Pattern Matching

April, 2004: Reformatting Text Using Pattern Matching

1  ./pretty --width=64 --left --newline gettysburg.txt 
2  ./pretty -w=64 -l -n gettysburg.txt 
3  ./pretty -w 64 -l -n gettysburg.txt 
4  ./pretty -w 64 -n gettysburg.txt 
5  cat gettysburg.txt | ./pretty --width=64 --left --newline 

1  Four score and seven years ago our fathers brought forth on this 
2  continent, a new nation, conceived in Liberty, and dedicated to 
3  the proposition that all men are created equal. 
5  Now we are engaged in a great civil war, testing whether that 
6  nation, or any nation so conceived and so dedicated, can long 
7  endure. We are met on a great battle-field of that war. We have 
8  come to dedicate a portion of that field, as a final resting 
9  place for those who here gave their lives that that nation might 
10  live. It is altogether fitting and proper that we should do 
11  this. 

Example 1: Left-justified output. Any of the five lines at the top will produce the output shown. You may omit --left (or -l) if you want your line to be left-justified, since it is switched on by default; see line 4 at the top.
