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.
