Grep for a pattern based on another patter
hi,
I have looked at many grep threads and am unable to find something like this: please help.
I have a file which is generated from a report generator and i am trying to load a whole lot of specific data into a table for the users. One field is causing me problems.All the rest i can manage.
I want to grep lines with date: (grep "date:" filename)..
however i want those dates only where there is a TEST in the 7th line below it and before the next pattern(date
date: 01/01/2001
xx
yy
zz
aa
bb
cc
TEST
zz
date: 01/02/2001
xx
yy
zz
aa
bb
cc
NOTEST

date: 01/03/2001

yy
zz
aa
bb
cc
NOTEST
yy
date: 01/04/2001
