in reply to Limitations to chmod and performance

Technically, the underlying chmod(2) system call only takes two arguments (the mode and the path). So no matter how many filenames you pass to perl's chmod it's going to devolve into multiple system calls somewhere underneath anywhere.

    On a linux box, this is easily illustrated by the following experiment (better carried on the /tmp directory):

     strace -e trace=file perl -e 'chmod 0777, "a".."z"' 2>&1 | tail -26

    One will see 26 chmod system calls.
