Using grep display lines of context before back to the first line matching something else before the matched...
So say I find a match with grep -e and I want to print all the lines from the match back to another match, like ---- for instance.
Is that possible, or do I have to use another command like awk or something to do that?
Like for instance, if I have the following file:
----
Ticket Number: 5465415312
Software Services
Notepad
Text
Description:
My Notepad won't type text.
The output should be like:
----
Ticket Number: 5465415312
Software Services
And it matches again up back to ---- from Software Services
text-processing awk grep

Please proof read. This question is very unclear, and lacks grammar. As such and answers would be guesses at what you want.

Awk is probably a better tool for what you want. Hard to tell from what you posted and if your file is or is not of uniform syntax

Nice use of sed, but the op is asking to print lines before or after matching a (single) pattern (I am not sure exactly) not matching multiple patterns or print lines between two patterns (a job for awk IMO).

@Panther This is thesedway of doing it. The question implicitly talks about two patterns. One pattern to trigger output and another to delimit from where the output should start.

That is, empty the string saved in lines every time we hit a line of four dashes. Then always append the current line to lines, and print the contents of lines when we find the "trigger" line in the input data.
