Find dont exclude folder

postcd · 08-22-2014, 11:10 AM

in my bash script i have this command:

Quote:

/bin/nice -n 19 /usr/bin/ionice -c2 -n7 find $wheretosearch -type f -size -800k -mmin -1440 ! -path "*backup*" ! -path "*/sys/*" ! -path "*/usr*" ! -path "*/proc/*" ! -path "*/task/*" -exec grep -l "$phrasse" {} \; >> $outputfile

as you see im trying to exclude folders like "proc" and "task" from the search, but when i execute script, it returns things like:

Quote:

find: /vz/root/240/proc/15889/task/15976: No such file or directory
find: /vz/root/240/proc/15889/task/16070: No such file or directory
find: /vz/root/240/proc/15889/task/16092: No such file or directory
find: /vz/root/240/proc/15889/task/16105: No such file or directory
find: /vz/root/1140/proc/1/task/1: No such file or directory
find: /vz/root/1140/proc/1170/task/1170: No such file or directory
find: /vz/root/1140/proc/1437/task/1437: No such file or directory

But when i exclude "sys" folder same way as proc, it woks to be excluded, but proc still showup

so im asking what is wrong on that command? thx

That's part of how find does its thing. To get rid of the errors, just redirect them with:

Quote:

2>/dev/null

thx, but kindly please tell me why find dont skip that folders. my aim is to decrease server load by skipping that folders, how i can make find to skip folder and dont waste time by working with it?

Ah. If you want to actually 'ignore' the directories and everything under it, you'll need to use 'prune' as find is not smart enough to NOT delve into an ignored directory.

I think the find option you are looking for is -prune. To my understanding the "not path" does not exclude the way that "prune" does.

Thanks for an advice, i modiffied the command to contain "-prune" instead, please is this correct?

Quote:

/bin/nice -n 19 /usr/bin/ionice -c2 -n7 find $wheretosearch -type d -name proc -prune -o -path "*proc*" -prune -o -path "*backup*" -prune -o -path "*/usr*" -prune -o -path "*/sys/*" -prune -o -size -800k -mmin -1440 -exec grep -l "$phrasse" {} \; >> $outputfile

the command should output last 24 hours modiffied files containing $phrasse into file $outputfile ..

I believe prune is more of an action, like -print is. So it comes after what you want to prune. For example:

Quote:

find [path] [stuff to prune] -prune

Quote:

find / -type d -path "/proc" -prune

I'm not sure that you need as many pattern matches either, with the *word*. But of course I don't know your file system, or the exact purpose of your find. But I say, use what was discussed here, play around with the output and see if it meets your needs. I also would say to many try a few conditions manually, make sure they do what you want, then tie them together into your script.

If you had thought about the information provided in your other thread http://www.linuxquestions.org/questi...es-4175515772/
then you might have realised that you will do better by grouping what you want to prune into a single expression

Code:

find $wheretosearch \( -path "*proc*" -o -path "*backup*" -o -path "*/usr*" -o -path "*/sys/*" \) -prune
 -o \( -size -800k -mmin -1440 \) -exec grep -l "$phrasse" {} \;
