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:
---------- Post updated at 06:25 PM ---------- Previous update was at 06:22 PM ----------
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----
------end of file---------

hmmm...interesting...isn't the record separator a newline now?
What if one sentence spans multiple newlines? Won't it be counted as two or more sentences?
Also, I don't understand exactly what the sub command is doing?
If what you want to do is separate records at points where the last character on a line is a <period>, <question-mark>, or <exclamation-point>, you probably want to use:
as rdrtx1 suggested.
Using RS="[.?!;:]" splits records on <period>, <question-mark>, <exclamation-point>, <semicolon>, and <colon> anywhere on a line.
Using RS="[^\"Mr.\"][.?!]" splits records on any two character sequence where the first character is not a <backslash>, <double-quote>, <uppercase-M>, <lowercase-r>, <period>, <backslash>, or <double-quote> and the second character is a <period>, <question-mark>, or <exclamation-point>. This ERE makes no sense to me for this use.
If, in addition to splitting when a set of characters is found at the end of a line, you also wanted to find that set of characters followed by two <space> characters (which is the common way of separating sentences in old fashioned text files), you could use:
Note that most of the above is talking about gawk and does not necessarily apply to other standards-conforming versions of awk. The standards state that it if more than one character is assigned to RS, it is unspecified whether RS is treated as a multi-character ERE that acts as the record separator or only the 1st character assigned to RS acts as the record separator. If RS is set to an empty string, the record separator is a sequence of two or more adjacent <newline> characters.
The default record separator is a <newline>. When RS is set to something other than a <newline>, <newline> (in addition to whatever FS is set to) is a field separator.
These 2 Users Gave Thanks to Don Cragun For This Post:
I'm trying to capture an english sentence in a record.
This sentence could be very long and span multiple lines in a file.
My perfect record separator would be a period, exclamation point, question mark, semicolon or colon.
However, my code sees the word "Mr." it thinks that's the end of the sentence because of the period that is part of Mr. So I want it detect that "Mr." is NOT part of the record separator.
Semantically:
Not (Mr.) but ok with any of these [.!?;:]
But syntactically I don't know how to do this, I'm trying like this:
But its not working?

Hello world,
I was wondering if there is a nicer way to write the following code (in AWK):
awk '
FNR==NR&&$1~/^m$/{tok1=1}
FNR==NR&&$1~/^m10$/{tok1=1}
' my_file
In fact, it looks for m2, m4, m6, m8 and m10 and then return a positive flag. The problem is how to define 10 thanks... (3 Replies)
