Hello gurus - I must be missing something, or there is a better way - pls enlighten me
I'm on a Solaris 10 vm running the following pipeline to reduce some apache logs (actually lynx dumps of /server-status/ when threads are above a threshold) to a set of offending DDoS IP addresses.
From the uniq manpage -
So why am I getting duplicate lines in the uniq output?
thanks

I have a project where I have to use bzcat to uncompress a file and use that output as the data to run another program on.
I understand that you would do (bzcat filename.bz2 ! program name) but then how do you access that data in the c program??? Please help thanks (2 Replies)
Does anyone know how to answer this? I have tried many different commands, I just cant get it right.....
Search the file 'data' for all of the lines that contain the pattern 'unx122'
and put those lines in the file 'matches'. (2 Replies)
I've got a very ugly pipeline for analyzing web server logs (but nevermind the application; I've come across this in other scripts as well). I want to nicely comment the steps in the pipeline, but I can't seem to do it.
I know, for instance that in csh/sh/bash, a # begins a comment, and any... (2 Replies)

uniq
UNIQ(1) BSD General Commands Manual UNIQ(1)NAME
uniq -- report or filter out repeated lines in a file
SYNOPSIS
uniq [-c | -d | -u] [-i] [-f num] [-s chars] [input_file [output_file]]
DESCRIPTION
The uniq utility reads the specified input_file comparing adjacent lines, and writes a copy of each unique input line to the output_file. If
input_file is a single dash ('-') or absent, the standard input is read. If output_file is absent, standard output is used for output. The
second and succeeding copies of identical adjacent input lines are not written. Repeated lines in the input will not be detected if they are
not adjacent, so it may be necessary to sort the files first.
The following options are available:
-c Precede each output line with the count of the number of times the line occurred in the input, followed by a single space.
-d Only output lines that are repeated in the input.
-f num Ignore the first num fields in each input line when doing comparisons. A field is a string of non-blank characters separated from
adjacent fields by blanks. Field numbers are one based, i.e. the first field is field one.
-s chars
Ignore the first chars characters in each input line when doing comparisons. If specified in conjunction with the -f option, the
first chars characters after the first num fields will be ignored. Character numbers are one based, i.e. the first character is
character one.
-u Only output lines that are not repeated in the input.
-i Case insensitive comparison of lines.
DIAGNOSTICS
The uniq utility exits 0 on success, and >0 if an error occurs.
COMPATIBILITY
The historic +number and -number options have been deprecated but are still supported in this implementation.
SEE ALSO sort(1)STANDARDS
The uniq utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
HISTORY
A uniq command appeared in Version 3 AT&T UNIX.
