List complete nodes which have a given child using sed.
View list_dependency_graphs_sed.sh
# sometimes we have a hierarchical list and we want to print all of the nodes
# that have a certain child, simple regular expression will only yield the child
# not the whole node. We can use sed to recover the whole node.
#
# let's say we want to recover all packages in pipenv graph that use pandas.
# /^ /!x{...}
# all of lines which do not start with a space are at the top of the
# hierarchy, swap them with the hold space. The hold space has now the node
# and the pattern space contains the contents of the hold space. Execute all
# commands between brackets.
