Hi Don Cragun,
I have log file which is mixed of all users, so perticular user log not getting from common log file. I have already captured lines based on userid. But thread I wanted to get in one variable. So here thread value is in between squre brackets after colon ( : ).
I repeat:
What are you going to do with this variable with hundreds of thousands of values separated by vertical bars in it once you get it? Now that you've said you want to get rid of duplicates, maybe it is only thousands of elements in the list instead of hundreds of thousands, but it still seems like you are focusing on an output format that is going to make it hard for you to use the results!
After you answer that question, also answer the following:
- Do you care if the values are sorted, or do you just want to be sure your list has no duplicates?
- Is it OK if the list separator is a <newline> character instead of a vertical bar? (If not, explain why!)
If you refuse to answer these three simple questions, I feel that we are all wasting our time in this thread.

Hi
First apologies if this has been raised before.
I've got the following in a ksh script:

For some reason this does not work. But if I remove the double square brackets to:

This works.
I thought ksh supported the ]. Or is there more to it?
Thanks in advance. (3 Replies)

QUIZ(6) BSD Games Manual QUIZ(6)
NAME
quiz -- random knowledge tests
SYNOPSIS
quiz [-t] [-i file] [question answer]
DESCRIPTION
The quiz utility tests your knowledge of random facts. It has a database of subjects from which you can choose. With no arguments, quiz
displays the list of available subjects.
The options are as follows:
-t Use tutorial mode, in which questions are repeated later if you didn't get them right the first time, and new questions are presented
less frequently to help you learn the older ones.
-i Specify an alternative index file.
Subjects are divided into categories. You can pick any two categories from the same subject. quiz will ask questions from the first cate-
gory and it expects answers from the second category. For example, the command ``quiz victim killer'' asks questions which are the names of
victims, and expects you to answer with the cause of their untimely demise, whereas the command ``quiz killer victim'' works the other way
around.
If you get the answer wrong, quiz lets you try again. To see the right answer, enter a blank line.
Index and Data File Syntax
The index and data files have a similar syntax. Lines in them consist of several categories separated by colons. The categories are regular
expressions formed using the following meta-characters:
pat|pat alternative patterns
{pat} optional pattern
[pat] delimiters, as in pat[pat|pat]pat
In an index file, each line represents a subject. The first category in each subject is the pathname of the data file for the subject. The
remaining categories are regular expressions for the titles of each category in the subject.
In data files, each line represents a question/answer set. Each category is the information for the question/answer for that category.
The backslash character (``'') is used to quote syntactically significant characters, or at the end of a line to signify that a continuation
line follows.
If either a question or its answer is empty, quiz will refrain from asking it.
FILES
/usr/share/games/quiz The default index and data files.
BUGS
quiz is pretty cynical about certain subjects.
