./Queen/(1986)/Innuendo/02.One vision.mp3
./Queen/(1986)/Innuendo/03.One vision.mp3

I want to display above line as:

01.One vision.mp3
02.One vision.mp3
03.One vision.mp3

I tried with:

  sed -i 's/^[^.$/]/ /g/

    sed -i 's|/|\n/; /\n/D' will progressively chop off chunks before / till the time there's no / left and what remains is the basename of the .mp3s

Your main problem is that you're trying to use / as a separator, when / also is a character you'll be parsing.

You'll need to use a different separator, such as a pipe. Match everything and a /, then use \( and \) (capture groups) delimiting the part you want to extract, and use \1, rendering that group:

echo "yourstring" | sed 's|.*/\([^/]*\)$|\1|'

You may have it working without capture groups: just dropping everything until the last /:

echo "yourstring" | sed 's|.*/||'

  • You can also backslash escape the slash in the regex and still use slashes for separators, ie. sed 's/.*\///', but it can be a pain in the ass to read.

Why not use basename for this? For example:

for file in *mp3; do basename "$file"; done

    It appears that OP wants to modify a file in place (see the -i flag in their example).
