Hi Gull04,

I tested your variant with this...

Code:
stomp@box:~/tmp$ find a
a
a/a.wav
a/A.wav
stomp@box:~/tmp$ find ./ -name 'a.wav' -o -name 'A.wav' -printf '%h\n'
./a
stomp@box:~/tmp$

...and I'm wondering why I have only 1 result. I would expect 2 results, as I understand the command like this: "Search for a file name a.wav or A.wav and print the corresponding parent directory". So why only 1 result here?

XXX:[XXX]/voip/old #

in none of the founded folders are both files together: unavail.wav & unavail.WAV.
just one of them exist in them:


Code:
XXX:[XXX]/voip/old # ll 7325
insgesamt 12
drwxr-xr-x 2 root root 4096  5. Aug 2011  INBOX
-rw-r--r-- 1 root root 6040  5. Aug 2011  unavail.WAV
XXX:[XXX]/voip/old # ll 5863
insgesamt 12
drwxr-xr-x 2 root root 4096  5. Aug 2011  INBOX
-rw-r--r-- 1 root root 6040  5. Aug 2011  unavail.WAV
XXX:[XXX]/voip/old # ll 3339
insgesamt 20
drwx------ 2 root root  4096  5. Aug 2011  INBOX
-rwx------ 1 root root 12670  5. Aug 2011  unavail.WAV
XXX:[XXX]/voip/old # ll 96964
insgesamt 8
drwxr-xr-x 2 root root 4096  5. Aug 2011  INBOX
-rwx------ 1 root root 3310  5. Aug 2011  unavail.WAV
XXX:[XXX]/voip/old #


so
Code:
find . -name 'unavail.wav' -o -name 'unavail.WAV' | tr A-Z a-z | sort | uniq -cd

worked fine

Hi,

I'll suggest that it's the way your search parameters are configured, as a simple example see below;

Code:
/-> touch a.txt A.txt
 /-> find / -name "[a,A].txt" -printf '%h\n'
/home/e434069
/home/e434069
 /-> find / -name a.txt -o -name A.txt -printf '%h\n'
/home/e434069
/->

As you can see there are implications for how you configure the find with the or option.

Regards

thank you very much. i will work on it =)

Hi,

You can change the find to;

Code:
find / -name "unavail.[W,w][A,a][V,v]" -printf '%#m %u %h\n'

A little bit messy maybe, I'm sure someone will know a better way of doing this.

Regards

The reason for above single item output is "operator precedence". man find:
Quote:
Operators
Operators join together the other items within the expression. They include for example -o (meaning logical OR) and -a (meaning logical AND). Where an operator is missing, -a is assumed.
.
.
.
Please note that -a when specified implicitly (for example by two tests appearing without an explicit operator between them) or explicitly has higher precedence than -o. This means that find . -name afile -o -name bfile -print will never print afile.
So above command reads find / -name a.txt -o \(-name A.txt -printf '%h\n' \) as (implied) -a precedes -o. Run
Code:
$ find  \( -name a.txt -o -name A.txt \) -printf '%f\n'
A.txt
a.txt

to overcome the problem.

Thanks Rudi,

I finally understood this now, so I'm at last able to use that find ... -prune thing now after 25 years(was a great mystery to me) ;-)
