I have to move 300000 files of 500000 (example filename =*2002*.PDF)
from a directory to another .
How can i do?
when i make a list with ls command ,i obtain the parameter list is too long.

This should create a list of files with the move command against it.

while `ls -l *.pdf | awk '{print $9}'` in fileName
do
echo mv "$fileName" /destination_directory > mvfile.bat
done

Once the above is done, chmod the mvfile.bat to executable and run the script.

i prove it , but it's not ok.Help

simplest solution (run it from relevant dir):

find . -type f -name '*.pdf' | awk {'print "mv "$1" /otherdir"'} | sh

or the simplest ever(run it from relevant dir):

find . -type f -name '*.pdf' -exec mv {} /otherdir \;
