Problems with "grep -vf", and exclusion files
OK, this really has me bolluxed.

I'm using Mac 10.6.8, and I'm trying to do simple analysis of my Apache logs in Unix. Let's call that text file "log".

Now I want to remove from that file all lines with incomplete GETs, so I do

Code:
grep -vf exclude log > out

where the file "exclude" has lines (one each) for 206 , 304 , 403 , 404 , 405 , 500 (included spaces). Those are status codes whose lines I want to remove from the log file. That works great.

Oh, I'll get rid of requests for mp3s too. So I add to that exclude file a line with "mp3" in it. I run the command, and it goes off in never-never land.

If I use an exclude file with just "mp3" in it, it works fine. Lines containing "mp3" are removed.

If I use an exclude file with "mp3" and "invitation" it works fine. Those lines are removed.

But if I use an exclude file with three or more lines of alphabetical characters, like "mp3, "invitation", and "pdf", it goes off into never-never land.

The rule seems to be that the "exclude" file works great with a list of numbers, OR with two or less words (as in, not numbers). This seems just nuts. What's going on??? I have basic Unix expertise. Is this a Mac peculiarity, or is there something else going on?

mp3cut

MP3CUT(1)							   User Command 							 MP3CUT(1)

NAME

       mp3cut - cut and assemble MP3 files

SYNOPSIS

       mp3cut  [ -o outputfile ] [ -T title ] [ -A artist ] [ -N album-name ] [ -t [hh:]mm:ss[+ms]-[hh:]mm:ss[+ms] ] mp3file [[ -t ...	] mp3file1
       ...]

DESCRIPTION

       The mp3cut utility cuts and assembles MP3 files according to the time specifications given on the command line. The mp3 output  is  written
       to  the	outputfile.  If  no outputfile is given on the command-line, the name for the outputfile is created from the name of the first mp3
       file by adding output.mp3 at the end. The -t flag specifies which part of the mp3 file following it will be extracted.

OPTIONS

       -o outputfile
	      Specify where the output is to be written.

       -T title
	      Specify the title ID3 tag for the output file.

       -A artist
	      Specify the artist ID3 tag for the output file.

       -N album-name
	      Specify the album name ID3 tag for the output file.

       -t [hh:]mm:ss[+ms]-[hh:]mm:ss[+ms]
	      Specify which part of the following mp3file will be included in the output file.

		    hh	= hours
		    mm	= minutes
		    ss	= seconds
		    ms	= milliseconds

	      If the starting time is omitted, 00:00:00+00 is used as starting time. If the ending time is omitted, the end of	the  MP3  file	is
	      used as ending time.

EXAMPLES

       mp3cut -o output.mp3 -t 23:42+500-01:23:42+750 input.mp3
	      Cut  the	segment  from  23  minutes,  42  seconds  and 500 milliseconds to 1 hour, 23 minutes, 42 seconds and 750 milliseconds from
	      input.mp3 and write the output to output.mp3.

       mp3cut -t 00:01-00:02 input1.mp3 -t -15:23 input2.mp3 -t 9:87+500- input3.mp3
	      Append the segments from input1.mp3, input2.mp3 and input3.mp3 and write the output to input1.output.mp3.
