use sed to get a list of different paths up to a point

Question

I have a list of filepaths that look like this

abc/def/ghi/jl/r1/r2
abc/def/ghi/jl/r9/r11
abc/nyc/ghi/jl/r3/r4/r5
abc/nyc/ghi/jl/pan21/nab11
def/kyn/ghi/jl/r6
...

all paths have the sub-paths /ghi/jl/

I would like to get a list of different paths ending at /ghi/jl/ so for the example above I would get

abc/def/ghi/jl/
abc/nyc/ghi/jl/
def/kyn/ghi/jl/

Can this achieved with sed (or something similar)? I tried

sed 's//ghi/jl/.*//ghi/jl//' listfile

but didnt quite get it.

Answer 1

perl -ne '/(^.*?/ghi/jl)/; print "$1 ";' listfile | sort -u

should do the trick.
