No it didn't work Smilie

It broke the file that was working.
I have a file without any "Mr." words.

By adding your suggestion, even the file without any "Mr." words stops working.

For example, it reads "one." as "on", "two." as tw, "three" as "thre".

This is the same as what was happening with my attempt below too.

Here's my full code:

Code:
#!/bin/bash

BEGIN {
       RS="[.?!;:]"           #       There is a problem with Mr. and Mrs. 
       maxWords=0
      }

{

if (maxWords<NF) 
     { 
        maxWords=NF
        longestSentence = $0
     }

for (i=1;i<=NF;i++) 
        a[$i]++

}

END{ 
      i=1;
      for(k in a) 
      {
        print i, k, a[k];
        i++;
      }
      print
      print("There were", NR, "sentences and the longest sentence had", maxWords, "words and there were", length(a), "unique words")
      print ("The longest sentence was:", longestSentence)
}

And the test file I'm using, which works fine as the code is above, but when I start changing the RS expression, even this file which has no "Mr." stops working.

----start of file----
Code:
one.
two two. 
three three three!
four four four four five five five five five.
six six six six six six?

------end of file---------

set_color(1)							       fish							      set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
