Unix Find with exec option.
All,

I am using following find command to see all the files with specified pattern :

Code:
find /exp/source -exec grep -li "SIT_MARKET" {} \;


say , the /exp/source has n number of subdirectories and each subdirectory has its own directory tree. If this is the case I will get a result like this :

Code:
 
/exp/source/MARKET/ver1.0/source/code/prod/SIT_MARKET.sql
/exp/source/MARKET/ver1.0.1/source/code/prod/SIT_MARKET_SIT.sql
/exp/source/MARKET_NEW/ver1.0/source/prod/SIT_MARKET.sql
/exp/source/TEST/code/SIT_MARKET_TEST.sql

Here my need is to restrict the find list to only the first line. The find should stop after printing the first line.

Is there way to achieve this ? Your help in this regard is highly appeciated.

Thanks,
-M

re-direct these o/p to a tmp file and then dispaly your number of outpot by using head command. and after display remove that temp file.

Thanks for your reply.

This solution will not work for me. My aim is to reduce the traverse happeing to the find command by stopping the find command once after getting the first result itself.

Thanks,

You may try something like this:

Code:
perl -MFile::Find -le'
  ($pattern, $dir) = @ARGV;
  find { 
    wanted => sub {
      return unless -f;
      $f = qx/grep -i "$pattern" "$_"/;
      print $File::Find::name and exit 
        if $f;      
        }
    }, $dir
  '  SIT_MARKET /exp/source

pipe it through head, then. Once it gets enough results, head quits, killing find with SIGPIPE.

I'm not able to get it work that way when -exec is present ..., I might be missing something, of course.

OK, it seems to work with xargs:

Code:
{ find /exp/source -type f | xargs -l grep -li SIT_MARKET | head -1 ;} 2>/dev/null
