writing file names from subdirectories to a csv file in linux

Question

Previously I have asked a very similar question but it was only for one subdirectory writing files in a subdirectory to a csv file and save it to parent directory in linux command line. I have a directory called 'dir', and there are 5 subdirectories in it, sub1, sub2,..sub5. Each sub directory has many files in it. I would like write to list of files from all subdirectories to a CSV file and save it to in 'dir' directory with a command line on linux. My code does that except I only want the filenames (name1,name2 etc) but it writes the full filenames with path (./sub1/name1,./sub1/name2, etc ). The command line I am using inside the dir folder is;

dir$ find . -type f  > names.csv

Answer 1

Since you've tagged your question 'Linux', I assume you have GNU find - in which case you can use

find . -type f -printf '%f\n' > names.csv 

From man find:

          %f     File's  name  with  any leading directories removed (only
                 the last element).

Answer 2

dir$ find . -type f -execdir basename {} \; > names.csv

Explanation

• -execdir performs the following command for each result.
• basename {} \; remove the part before the final /. The {} substitutes for each directory found. See man find for more info.
