not working on xigmanas (FreeBsd)

[rudiratlos]

lsattr and perl is not installed on xigmanas platfform.

lsattr can be installed on xigmanas (login via ssh) by:
pkg install e2fsprogs

perl is only used in teh script to calc the percentage.

just replace line 72:
progress_percent=$(perl -e "printf('%0.2f', ${current_index}*100/${file_count})")
with
progress_percent=$((${current_index}*100/${file_count}))

perl was introduced in #24 , if there is a truly platform agnostic alternative, I would be more than happy to merge a PR.
