How to use the parallel command along with find command in bash
0
Trying to process a large list of files (~1000+)
The follow is a script that I am using..
for i in (find ./ -type f "*.properties");
do
native2ascii -encoding UTF8 $i $i ; //java native2ascii
done;
This will take a really long time to complete. Wondering is there a better way that I can leverage the commend parallel or other command in bash to shorten the time it takes?

why not?
find ./ -type f "*.properties" |
parallel -j 4 native2ascii -encoding UTF8 {} {}
{} is for the replacement of input, adjust -j to match your CPU utilization.

-jdefaults to number of cores. Do not quote {} twice. It is unsupported and will sometimes fail in newer versions. So use this instead:parallel native2ascii -encoding UTF8 {} {}
