find exec to grep problem

bvdv · 08-06-2013, 03:41 PM

Hello all,
thanx in advance for trying to help me.

my problem is that i cant direct my output to i file.
i think it has to do with the space in my directory/filenames
the output i get on the screen(green) is what i want in the test.txt file

again thx for all help

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?

bvdv · 08-06-2013, 04:01 PM

when i execute the command (blue)
i get the green text on the screen.
what i want is the green text in a file ( here test.txt) ( so redirect green in the test.txt file)

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?

bvdv · 08-06-2013, 04:24 PM

$ ls test.txt
test.txt
sorry
$ ls -l test.txt
-rw-rw-r-- 1 bert bert 0 aug 6 23:23 test.txt

astrogeek · 08-06-2013, 04:26 PM

That was

Code:

ls -l test.txt

You write faster than I do!

bvdv · 08-06-2013, 04:29 PM

same for >>

$ sudo find '/home/bert/Music/The Offspring' -iregex ".*\.$mp3\|ogg\|flac\|ape$" -exec /home/bert/Documents/bmpcount/usr/lib64/bpmdj/bpmcount {} + | grep "bert" >> test.txt

$ ls -l test.txt
-rw-rw-r-- 1 bert bert 0 aug 6 23:23 test.txt

astrogeek · 08-06-2013, 04:30 PM

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 {}

bvdv · 08-06-2013, 04:31 PM

one
the bpmcount executable is in the /home/bert/Documents/bmpcount/usr/lib64/bpmdj/ directory

Bert

astrogeek · 08-06-2013, 04:35 PM

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

[/EDIT]

Firerat · 08-06-2013, 04:41 PM

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

jpollard · 08-06-2013, 04:43 PM

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.

astrogeek · 08-06-2013, 04:57 PM

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.

bvdv · 08-06-2013, 05:14 PM

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"

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,
