How to add a custom path to : " ls -d */ "

Issue : The code works fine, it lists folders with "numerical names" in a reversed order, however I would have to be in the same directory. I would like to add a custom path to it so that I do not have to be in the same directory.

ls -d */ |  cut -d '/' -f 1 | sort -nr

I tried adding " /test/path " to the code above, but without success.

ls -d */ /test/path/ |  cut -d '/' -f 1 | sort -nr

Update : I do not know why "test2" is being printed at the bottom in this scenario. I am using SliTaz Linux 5.0 I can not figure out the shell version. 

root@s1:/# mkdir /test
root@s1:/# mkdir /test/test2
root@s1:/# cd /test/test2/
root@s1:/test/test2# mkdir 1 2 3 10
root@s1:/test/test2# touch test.txt
root@s1:/test/test2# ls -d /test/test2/*/ | awk -F'/' '{print $(NF-1)}' | sort -nr
10

test2
root@s1:/test/test2#

Update 2 : On my cloud server which uses "Alpine Linux" version "3" I believe, there does not seem to be a problem, the code works ok.

test:/# mkdir /test
test:/# mkdir /test/test2
test:/# cd /test/test2
test:/test/test2# mkdir 1 2 3 10
test:/test/test2# touch test.txt
test:/test/test2# ls -d /test/test2/*/ | awk -F'/' '{print $(NF-1)}' | sort -nr

test:/test/test2#
Solution 
  • ls -d /test/path/*/ |  cut -d '/' -f 1 | sort -nr

    Although cut won't work the way you intend to use it.

    Instead use this:

    ls -d /test/path/*/ | awk -F'/' '{print $(NF-1)}' | sort -nr

    Also to avoid nullglob, set this before:

    shopt -s nullglob

    So that if no directories exist, it doesn't result into error.

    I am not sure about the reason the above command doesn't work on SliTaz Linux 5.0, but as discussed, this can be done instead:

    cd /test/path/ ; ls -d */ | awk -F'/' '{print $(NF-1)}' | sort -nr ; cd "$OLDPWD"

    or

    (cd /test/path/ ; ls -d */ | awk -F'/' '{print $(NF-1)}' | sort -nr)
