I have a parent directory with multiples subdirectories like this



Parent_directory
subdirectory_1
perlscript.pl
file.fasta
subdirectory_2
perlscript.pl
file_2.fasta


And I would like to run the perl scipt in each subdirectory. I'm trying with the next command



find . -type d | while read d; do perl hoz-3-v1c.pl $d/* ; done


but the output is directed to the parent directory and I want the output in each subdirectory

It looks like you don't have to bother with find at all in this instance.



for dirpath in Parent_directory/*/; do
( cd "$dirpath" && perl perlscript.pl *.fasta )
done


This assumes that the Perl script is always called perlscript.pl (as in your example directory layout) and that correct way to run your Perl script inside each directory is



perl perlscript.pl *.fasta


In the loop above, the parentheses creates a subshell. This prevents the cd from affecting the rest of the script and we don't have to cd back out of the directory after running the Perl script.



The loop will iterate over all subdirectories of Parent_directory and execute the given commands in each.

    If your find supports the -execdir predicate (GNU, BSDs at least):



    find . -name perlscript.pl -execdir sh -c 'exec perl ./perlscript.pl *.fasta' ;


    searches for the perlscript.pl files and runs perl on it with the current directory set to the directory where it's found.



    We need a shell to expand the *.fasta glob.
