ok, I'm solved It's was very simple

Code:

cd /var/www/html/regia0/temp/f  #  here the solution
for file in *
do
mv "$file" $(echo "$file" | sed 's/[^A-Za-z0-9.]//g')
done;

[[ -z "$1" ]] && exit
dir="$1"

for file in ${dir}/*
do
 dr=${file%/*}
 fb=${file##*/}
 fa=${file##*/}
 echo $fa | read fa
 [[ "$file" = "$dr/$fa" ]] || mv "$file" "$dr/$fa"
done;
