Sorry,
i have overlooked your answer:
-n -- print only lines when asked
'/pattern/ -- if you match pattern
{g;1!p} -- then execute the following group of command
g -- overwrite the pattern space with the hold space
1!p -- print the pattern space if it is not the first lien
;h' -- this is executed on all lines and means save every line in the
hold space.
file -- the file to proceed.
What it does: a) it saves every line in the hold space, b) if your pattern
is matched, the pattern space -- the line with the pattern you searched --
is replaced by the line previously saved in the hold space -- that is the
line preceeding your pattern. Thus the pattern you searched is replaced by
the line preceeding it.
This sed-command should be the usable on all unixes.
If you have problems, please give concrete examples of what you are
searching for and the data in your file.

NAME
bwild - Bacula's 'wildcard' engine
SYNOPSIS
bwild [options] -f <data-file>
DESCRIPTION
This manual page documents briefly the bwild command.
This is a simple program that will allow you to test wild-card expressions against a file of data.
OPTIONS
A summary of options is included below.
-? Show version and usage of program.
-d nn Set debug level to nn.
-dt Print timestamp in debug output
-f <data-file>
The data-file is a filename that contains lines of data to be matched (or not) against one or more patterns. When the program is
run, it will prompt you for a wild-card pattern, then apply it one line at a time against the data in the file. Each line that
matches will be printed preceded by its line number. You will then be prompted again for another pattern.
Enter an empty line for a pattern to terminate the program. You can print only lines that do not match by using the -n option, and
you can suppress printing of line numbers with the -l option.
-n Print lines that do not match
-l Suppress lines numbers.
-i use case insensitive match.
