After generating a file with lines of text, I have to:
1) parse some of those lines based on a pattern I know (no regex
necessary, just a FS path)
2) once parsed from those lines I need the last n characters only
I am trying to use a one liner like:
cat "${IFL}" | grep "${DESC_DIR}" | tail -c+$_DESC_DIR
but this one liner repeats the output and the tail
Say the lines of text in IFL are:

I know the prefix:
[info] 123XYZ: /media/user/1234qwer/Algebraic_Geometry04/20231022040239/
I need as output:
Uppsala_Algebra/45_16.3_45MEB5h5H9Y
Uppsala_Algebra/46_17.1_LE_gl5RcDnY
Göttsche/17_9jKzwoBGFs8
Göttsche/18_plOUIOo91lI
Göttsche/19_TJ7yAiq8gEw
Göttsche/20_UMBEgb14uqw
