The /portable filename characters/ as defined by ANSI C are
a b c d e f g h i j k l m n o p q r t u v w x y z
A B C D E F G H I J K L M N O P Q R T U V W X Y Z
0 1 2 3 4 5 6 7 8 9
. _ -
prompt$ for file in *; do echo mv "$file" $(echo -n "$file" |tr -c '[a-zA-Z0-9_.-]' _ );done
Is what I'd use, the output of which I'd check very carefully for "bulletproofness" before using.
If you've got directories with dodgy names in a hierarchy then
find . -name "*"; while read dir; do
if [ -d $dir ]
I'm not sure if it's exactly what you want but I hope it helps.
