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

vorbiscomment
VORBISCOMMENT(1) Ogg Vorbis Tools VORBISCOMMENT(1)
NAME
vorbiscomment - List or edit comments in Ogg Vorbis files
SYNOPSIS
vorbiscomment [-l] [-R] [-e] file.ogg
vorbiscomment -a [ -c commentfile | -t "name=value" ] [-q] [-R] [-e] in.ogg [out.ogg]
vorbiscomment -w [ -c commentfile | -t "name=value" ] [-q] [-R] [-e] in.ogg [out.ogg]
DESCRIPTION
vorbiscomment Reads, modifies, and appends Ogg Vorbis audio file metadata tags.
OPTIONS
-a, --append
Append comments.
-c file, --commentfile file
Take comments from a file. The file is the same format as is output by the the -l option or given to the -t option: one element per
line in 'tag=value' format. If the file is /dev/null and -w was passed, the existing comments will be removed.
-h, --help
Show command help.
-l, --list
List the comments in the Ogg Vorbis file.
-q, --quiet
Quiet mode. No messages are displayed.
-t 'name=value', --tag 'name=value'
Specify a new tag on the command line. Each tag is given as a single string. The part before the '=' is treated as the tag name and
the part after as the value.
-w, --write
Replace comments with the new set given either on the command line with -t or from a file with -c. If neither -c nor -t is given,
the new set will be read from the standard input.
-R, --raw
Read and write comments in UTF-8, rather than converting to the user's character set.
-e, --escapes
Quote/unquote newlines and backslashes in the comments. This ensures every comment is exactly one line in the output (or input),
allowing to filter and round-trip them. Without it, you can only write multi-line comments by using -t and you can't reliably dis-
tinguish them from multiple one-line comments.
Supported escapes are c-style "
", "
", "\" and "
