not finding a match

[GoogleCodeExporter]

What steps will reproduce the problem?
1. logwarn -p /tmp/test.txt 'Error' 'ERROR'
2. it shows error
3. add text to /tmp/test.txt at the end of the file: 
ERROR
qweqwey

4. logwarn -p /tmp/test.txt 'Error' 'ERROR'
5. no error is found.

What is the expected output? What do you see instead?

What I am seeing, is that it's necessary in this example to add some 
non-matching text like qweuiqwe , BEFORE adding another matching text pattern. 
If you simply add, immediately and directly, some matching text to the end of 
the file, in this case "ERROR", it won't be detected.   some intervening 
characters are necessary.  

What version of the product are you using? On what operating system?

Ubuntu 12.04

Please provide any additional information below.

Please run the following script and tell me what it prints:

{{{
#!/bin/sh

rm -f logfile statefile
echo 'ERROR line #1' >> logfile
logwarn -f statefile -p logfile 'Error' 'ERROR'
echo 'ERROR line #2' >> logfile
logwarn -f statefile -p logfile 'Error' 'ERROR'
}}}

When I run this script it outputs:

{{{
ERROR line #1
ERROR line #2
}}}

which seems to contradict your assertion. I'm using openSUSE 12.2.

What does this script print for you on Ubuntu?

more information.  if I add "redis error" to the end of the file, it reports a 
match.

edis error

ah ha!  it's not getting that first character.

ok, I see.   in my tests, I was adding a newline.  Hitting enter.    However, 
if you don't hit enter on the last line, and then run this append testing, it 
works.    problem "solved", I guess.
