If I was trying to grep a zillion files at once and it wouldn't
let me I'd probably grep them one at a time.
For instance via the backtivck execution You might have:
my @matchedfiles = qx(cat `ls /files/` |grep $string);
# a really bad way to do this but for example's sake...
You could do:
for(`ls /files/`) {
if(`cat $_ |grep $string`) { push(@matchedfiles,$_); }
}
Then you are only greping one file at a time instead of a list of too many.
Of course what would be better is to use the readdir() functions to list the files
and open() and grep() combo to grep the contents. But the same principle applies.
Just make sure the barracuda folks says thanks for fixing their problem :)
