Remove characters between a special character and a word

Question

I have doing tons of research and can't seem to figure it out.

I am using sed and trying to process a file of paths

/path/to/somewhere/for-something.rar

I need to remove everything past the last / but not the / itself. Can anyone help me with this? I can never handle sed lol

Answer 1

Use dirname:

path=/path/to/somewhere/for-something.rar
dir="$(dirname $path)/"

Or use shell:

dir="${path%\/*}/"

Output:

$ echo "$dir"
/path/to/somewhere/

Answer 2

To find all "/..../file.rar" and print "/..../" in a file-of-paths you can use good old grep...

grep -Po '/\S+/(?=\S+\.rar\b)' file-of-paths
