sed with a regex starting with space and containing dash

Question

In bash I want to parse filenames of mp3 files where the separator between track number, artist and title is " - " (space dash space). The expected result is as follows: Title of the Track (Original Version - Long Edit)

My sed command as follows:

echo "03 - Artist name first-middle name - Title of the Track (Original Version - Long Edit)" | sed -E 's/^([^ - ]*[ - ]){2}//'

The result: Artist name first-middle name - Title of the Track (Original Version - Long Edit)

I'm stuck here and can't make " - " as one term. What am I doing wrong? Thanks for your hints!

Here sample data:

'01 - Skyway - Chillwave - Synthwave - Retrowave Mix.mp3'
'02 - Baldocaster - Astral Dive.mp3'
'05 - Jacket. and Shadowrunner - Deathtouch.mp3'
'06 - Night Drive - A Synthwave Mix.mp3'
'07 - Shadowrunner and Syst3m-Glitch - Eastbound Plane Mattaei (Original - Long Mix).mp3'

In the bash scriptI want to set the title variable as follows:

title=`echo ${filename} | sed -E "s/^([^${SEPARATOR}]*[${SEPARATOR}]){4}//"

where SEPARATOR is a variable as well containing e.g. " - "

Answer 1

A solution using parameter expensions.

$ filename="03 - Artist name first-middle name - Title of the Track (Original Version - Long Edit)"
$ filename="${filename#* - * - }"
$ echo "$filename"
Title of the Track (Original Version - Long Edit)
