May be a regexpression
May be a regexpression can do it easily.
A command like:
grep expression textfile.txt | tee newfile.txt
where expresion will say list me all lines which has 'a:' or 'b:' in it and now the newfile.txt will have all my interested lines.
with the parent names below their child names
{I some how have to get rid of the extra text like blah blah }
Can you point me how the regexpression should be like
