Let's say I have a file with a long nested array, that's formatted like this:
array( 'key1' => array( 'val1' => 'val', 'val2' => 'val', 'val3' => 'val', ), 'key2' => array( 'val1' => 'val', 'val2' => 'val', 'val3' => 'val', ), //etc... ); what I would like to do is have a way to grep/search a file, and by knowing key 1, get all the lines (the sub-array) it contains. is this possible?
Not with grep but you should be able to do it with awk or sed:
sed -n '/key1/,/)/p' file.txt If there are no more levels of nested arrays, then this should work:
awk '/key1/,/\)/' my_input_file Basically, it prints from key1 to next closing bracket ).
cat If it is a fixed number of items in the array, you can use the -A (lines after switch) with grep:
grep -A4 'key1' myfile -A NUM, --after-context=NUM Print NUM lines of trailing context after matching lines. Places a line containing a group separator (--) between contiguous groups of matches. With the -o or --only-matching option, this has no effect and a warning is given. There is also -B for before lines as well.
