Find in the current line and next line.

Shell Programming and Scripting

Hi,

I have lines that have pattern like this.
1)

productFamilyGroupIndex < Local.ProductFamilyGroup.capacity))

and
2)

 if (local.getProductFamilyGroup().size() >= Local.ProductFamilyGroup.
        capacity)

So, If I need to find the pattern

grep '\(< \|>= \)Local.*capacity' filename would search only one line.

But, I want it to print 1) and 2) as well. How can I do that?

I have also tried

pcregrep '(< |>= |> |<= )Local.*(capacity|\n.*capacity)' OscCabCreatePaSaNtwrkDenrm.java

egrep '(< |>= |> |<= )Local.*(capacity|\n.*capacity)' OscCabCreatePaSaNtwrkDenrm.java
2

if you have gun grep, then you can try below

grep -A 2 <pattern to be searched>  <file name>
3

grep -A2 would print only the matching line and the next line

grep '\(< \|>= \)Local.*capacity' filename -A2 will still print 1) and the next line.
But, it will not print 2) because the line 1 on 2) doesn't match.

I am looking for the pattern that matches 1) and 2)
1) and 2) are not subsequent lines. They are present at different locations in the code.

pcregrep -M '(< |>= |> |<= )Local.*(capacity|.$\n[ ]*capacity)' OscCabCreatePaSaNtwrkDenrm.java

From the man page of pcregrep

In particular, the -M option makes it possible to search for patterns that span line boundaries. What defines a line boundary is controlled by the -N (--newline) option

sed concoction:

sed -n '/Local\..*capacity/{p;d;};/Local\./{N; /Local\..*capacity/p;}' infile

I made some modifications to it, but I like the sed alternative. Thanks!
