Excluding a directory from a recursive search in ksh

vinay naik — Tue, 14 Jul 2009 10:01:37 GMT

Hello all,
I would like to avoid seaching through the .svn directory whenever I grep for a pattern.
For ksh, I generally use
find . -name "*" -exec grep {} \; -print

How do I "exclude" a particular directory from a recursive search ?

Thanks..

Hi:

One way:

# find . ! -path "./.svn/*" -type f -exec grep {} +

Regards!

Thanks James.
But I have multiple .svn in recursive directories. The solution excludes .svn only in the current directory.

Hi (again):

You didn't make that clear at the oneset, so try this:

# find . ! -path "*/.svn/*" -type f -exec grep {} +

Hi,
One more question..
How can I 'avoid' searching a pattern in binary files such as executables and libraries? Are there options to the 'find' or 'grep' commands to isolate search only in ASCII files?

-Thanks

find or grep dors not have switches to differentiate between ascii and binary files. you need to build a logic like :

for f `ls /tmp`
do
file ${$f} | grep -q text
r=${?}
if [ ${r} -eq 0 ]
then
#this is a text file either command script or ascii text
grep ${f
fi
done

We could leverage Perl, like:

# perl -MFile::Find -e 'find(sub{push @f,$File::Find::name if $File::Find::dir !~m{\.svn/} && -f $_ && -T _},".") ;@a=`grep -i $ARGV[0] @f`;print for sort @a' PATTERN

Specify your PATTERN to be matched as the argument to the script. Note that the '.svn' directory has its dot character escaped (backslashed) to signify that the dot is not a metacharcter in the regular expression match.

This script looks for files in the current directory but skips any that are not "text" ('-T') ones.

If you want to exclude all .svn directories and subdirectories, then the right option is -prune. Especially if you don't want find to search those subdirectories.

To use -prune:

Another approach, probably not one for the purists but one I find syntactically easier is to use xargs and grep.

find . | grep -v svn | xargs grep

I like it because you can iteratively tune the list of files with multiple "| grep -v pattern" until you get what you want and then pipe to xargs and grep for the pattern within the files you are looking for.

(I have never liked the -exec find syntax ;-)
