If I'm just inspecting a file I use less and the "/" command to search up
to the next occurrence of a regular expression. Use the "?" command to
search backwards.

Um
It's the first option described.
Thanks, all. I did actually look at the grep manpage but after a few
screenfuls it became tl;dr and I started just skimming. I suppose that
I skimmed too fast!

Can grep show the matching lines and the next N lines after a match?
For instance, I have a config file wit hthe following text:
[Tag h1]
foreground=#2e5a03
underline=double
indent=0
weight=PANGO_WEIGHT_BOLD
scale=2.25
I would ideally grep on "[Tag h1]" and have grep display the match and

Hi folks
I have the command "find . | xargs grep 'mailx'", to search all files
with "mailx" in contents. I wish to add a second condition that NOT
contains string sven.alu...@ubs.com on the same line.
Every file which contains "mailx", but not the string
sven.alu...@ubs.com in the same line.

Now that's cool, each case has to be separate so
grep -B 3 "D:" input.txt or even the actual volume string for
certainties sake is the ticket!

If the line counts are constant you could do the reverse:

Which would show the 3 lines above a line that

Old geek statement: If you think perl is the answer to a simple filter
question then think twice. You might be right, but it's likely smaller
faster tools already exist. And I say this as someone who has written
1000 line shell scripts and even bigger perl scripts; perl is good for
complicated

The scope of grep's view of the world is a single line. At any one
time, it knows nothing more.
If you need to deal with multiple lines, I suggest perl. Untested code:
