Is - /home/bert/Documents/bmpcount/usr/lib64/bpmdj/bpmcount - executable?

What output does it produce?

Explain what you mean by "can't direct output to file" - what is actually happening?

OK, sorry, I thought the green was what you wanted but were not getting anything...

I can only guess that the .../bpmcount is maybe writing somewhere other than stdout so that it is not seen by the pipe at all.

[EDIT]
What does ls -l test.txt say? test.txt isn't possibly a FIFO is it?

You write faster than I do!

Question:

Is this one path, or two separate scripts?

Code:
-exec /home/bert/Documents/bmpcount/usr/lib64/bpmdj/bpmcount {}

or

-exec /home/bert/Documents/bmpcount [SPACE] /usr/lib64/bpmdj/bpmcount {}

Is the bpmcount a binary or shell script?

If it is a shell script, and not too long, can you post it here?

My guess is that it is not writing to stdout, so grep never sees it.

[EDIT]
Try this
Code:
sudo find '/home/bert/Music/The Offspring' -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" -exec /home/bert/Documents/bmpcount
/usr/lib64/bpmdj/bpmcount {} + | grep "bert" 2> test.txt

just try adding 2>&1
Code:
sudo find '/home/bert/Music/The Offspring' \
            -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" \
            -exec /home/bert/Documents/bmpcount/usr/lib64/bpmdj/bpmcount {}\
             2>&1 + \
            | grep "bert" >> test.txt
Edit you probably don't even need the grep
Code:
sudo find '/home/bert/Music/The Offspring' \
            -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" \
            -exec /home/bert/Documents/bmpcount/usr/lib64/bpmdj/bpmcount {}\
             2>&1 + >> test.txt

In case it is not writing to stdout, you can find out if redirecting using "2>file" works (redirect stderr).

Assuming you are using bash of course. If csh/tcsh try ">&file" which will redirect both of them.

If redirecting stderr does not work (2>, 2>&1, etc.) you might check bpmcount to see if it is doing something screwy like writing to /dev/console or some such place.

sorry for the late reply
@astrogeek
sudo find '/home/bert/Music/The Offspring' -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" -exec /home/bert/Documents/bmpcount
/usr/lib64/bpmdj/bpmcount {} + | grep "bert" 2> test.txt
does not work no text in test.txt

@firerat
You are right about the grep the 2 lines of code produces the same test.txt(oragne color).
but not exactly what i want
as you can see there are lines with th progress thats why i used the grep for "filtering" the lines that does contains a directory with my name"bert"
105,469 /home/bert/Music/The Offspring/13 - Keep Them Separated.mp3.

but we are getting closer :-)

would tell us enough

going to use > , instead of >> ( replace instead of add to )
Code:
sudo find '/home/bert/Music/The Offspring' \
            -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" \
            -exec /home/bert/Documents/bmpcount/usr/lib64/bpmdj/bpmcount {}\
             2> test.stderr > test.txt +
you will get two files,
