[Message part 1 (text/plain, inline)]

Hello,

 I am not so sure that this is a bug but a limitation. I am using "du"
for a disk file listing/usage in the command:

du --all --time --human-readable --apparent-size $1;
printf "Total number of files: ";  find $1 -type f | wc -l;

But it seems to maximum out the file count to 38341

 So I am thinking that this is a limitation to the counter in "wc"?

 Just to let you know I have a script that takes a picture every minute
and stores it to a 1TB HD and deletes anything older than 31 days.
Total file count should be near 2,678,400 files.

You did not specify any problems with the above line pertaining to "du".

> printf "Total number of files: ";  find $1 -type f | wc -l;

The above line does not relate to "du", but to "find" and "wc".

I don't think so. You can easily check wc's counter by generating known
input, e.g. as follows:

$ yes | head -n80000 | wc -l
80000
$ yes | head -n2678400 | wc -l
2678400

For some random directory I find the following:

$ find . -type f | wc -l
124168

I do not see the limit you observed.

Best regards,
Erik
