Is there a Linux command that will return the file path of the bottom most dir.

I've tried the following commands: find /home/Alison/workspace/DirLevel1/DirLevel2/DirLevel3/DirLevel4/DirLevel5/DirLevel6/DirLevel7/ -type d


tree -dfi /home/Alison/workspace/DirLevel1/DirLevel2/DirLevel3/DirLevel4/DirLevel5/DirLevel6/DirLevel7/

Both these commands return:


As you can see in the case of:



It is returning /qvm/ as well as /qvm/a where I just want the bottom dir.

This question came from our site for professional and enthusiast programmers.

What if there are multiple paths at the same depth? Do you need both or just one? – thkala Sep 2 '12 at 16:38

This should do the job:

find . -type d | \
  awk -F/ '
    NF <= old_NF {print prev}
    {old_NF=NF; prev=$0}
    END {print $0}


find . -type d
./source/dir with space

Now the command from above gives:

./source/dir with space

Short explanation:

The plain find . -type d output is already sorted according to the directory structure. What you now want is those lines (=paths) that are immediatly before a line that has the same or less depth. And the last line (always).

This is what the awk command does. It splits input lines on the path separator (-F/), stores the number of fields and the line ({old_NF=NF; prev=$0}) and then compares the old number of fields to the current one and prints the stored line if number of fields is less than or equal (NF <= old_NF {print prev}). And it prints the last line always (END {print $0}).

The level won't always be the same so would need to be more flexible to get to the bottom level no matter how deep the path goes. – Colin747 Sep 2 '12 at 16:11
@Colin747 please see my updated answer... – Theodros Zelleke Sep 2 '12 at 16:39
Worked perfectly, thanks. – Colin747 Sep 2 '12 at 16:42
But i t wont work appropriately on such a case (or am I misunderstanding the question?): ./source ./source/siteA ./source/siteA/regionA ./a/very/long/path/to/some/where/else ./a this would only print the 4th line. – Sahand Mozaffari Sep 2 '12 at 16:57
@SahandMozaffari before find prints ./a/very/long/path/to/some/where/else it definitely prints ./a, ./a/very, ... that's why it works ;-) – Theodros Zelleke Sep 2 '12 at 17:19
