The [ ] is normally used for [A-Z0-9] etc., to represent a single character, which you probably know.

It would help to see some actual code. Otherwise, my best guess is the previous answer I gave.
Hello,
Thanks for your help.

Imagine i have several files with these forms :
exploitation_ora.log.2013-03-28.001
server.log.2013-03-28.tar.gz
After creating variables, i have this :
$type_$instance.log.$date.001
$type.log.$date.tar.gz

What's pattern matching notation or regular expression [????????] do i put to replace _$instance or nothing ?
Code:
$type_$instance.log.$date.001
$type          .log.$date.tar.gz
$type[????????].log.$date.*

For example, i can include this in a script.
Code:
find /usr -name $type[????????].log.$date.*

Have a nice day

nnstats

NNSTATS(1m)															       NNSTATS(1m)

NAME

       nnstats - display nnmaster collection and expire statistics

SYNOPSIS

       nnstats [ -lt ] [ -d month day ] [ -m month ] [ logfile ]...

DESCRIPTION

       nnstats	will  extract  the collection (C) and expiration (X) entries from the log file and calculate total and average number of articles,
       groups and elapsed time per day, per month, or for the duration of the whole log file.

       Normally only a summary for the specified period is printed.  If -l is specified, the statistics  for  each  day  in  the  period  is  also
       printed, and if -t is specified the summary is not printed.

       Normally the statistics is collected for all days in the log files (or the current log file if one is not specified).

       If  "-m	month" is specified, the statistics for that month is calculated.  The month is specified in normal date notation, i.e. a capital-
       ized three letter abbreviation like Jan, Feb, ...

       If "-d month day" is specified, the statistics for that date only is calculated and printed.

FILES

       ../Log	The log file

SEE ALSO

       nn(1), nnusage(1M), nnadmin(1M), nnmaster(8)

NOTES

       If nnmaster is run with options -LCX, nnstats will not work, because the necessary entries are not written to the log file.
