Hi,
I use cygwin to get bash-functionality on my windows machines.
I have a dirtectory tree, with various files at various levels, I'm looking for a script to create a csv in every folder downstream of the one I initiate the script in, with a list of the files in that folder, the csv is easy - just [ls > name.csv]

ls -al | tr -s '  ' ' ' | tr -s ' ' ','

mind you this will not work if any of the file names has a space in them.

you can do a

ls -Ral | tr -s '  ' ' ' | tr -s ' ' ','

to recursively go through directories

that only messes the output with a comma inbetween the dates. forget it .  if you want only the file names then why not

ls | tr -s "\n" ","

that gives only the file names as a csv value.

ls -R | tr -s "\n" ',' | tr -s "\/" "\n"

to have the directory names displayed on top of every line

most of the filenames and folder names have spaces.

Don't want comma between the names, just what "ls > name.csv" would do.

find . -type d -exec sh -c 'cd {}; pwd; ls > name.csv' \; worked great, but get confused with spaces in folder names.

Hmm.. will something like this do your job ?

#!/usr/bin/perl
open(I_FILE,"ls -R1 |") or die("Cannot get the directory list.");
open(O_FILE,">treelist.csv") or die ("Cannot create output file");
foreach $line (<I_FILE>) {
chomp($line);
@countdir = split ( "\/", $line);
$output = join(",",@countdir);
$cnt = @countdir;
$cnt2=1;
print O_FILE "$addcomma.$output";
$addcomma="";
while ($cnt2 < $cnt) {
       $addcomma=$addcomma.",";
       $cnt2=$cnt2+1;
}
}

find . -type d -exec sh -c 'cd "{}"; pwd; ls > name.csv' \;

adding the double quote before and after the {} should do the trick

Tested this :

#! /usr/bin/perl

open(I_FILE,"ls -R1 |") or die("Cannot get the directory list.");
open(O_FILE,">treelist.csv") or die ("Cannot create output file");

foreach $line (<I_FILE>) {
@countdir = split ( "\/",$line);
$output = join(",",@countdir);
$cnt = @countdir;
$cnt2=1;
if ($cnt > 1) {
$addcomma="";
print O_FILE "$output\n";
}
else
{
print O_FILE "$addcomma.$line\n";
}
while ($cnt2 < $cnt) {

$addcomma=$addcomma.",";
$cnt2=$cnt2+1;
}
}
