I have been removing spaces and a number of characters that cause problems in
filenames with the following:
#!/bin/bash
ls | grep " " >totototo
while [ -s totototo ]
do
rename " " _ *" "*
ls | grep " " >totototo
done
for CHR in "(" ")" "," "%" "'" ":" ";" "__" "_-"
do
ls | grep $CHR >totototo
while [ -s totototo ]
do
rename $CHR "" *$CHR*
ls | grep $CHR >totototo
done
rm -f totototo
done
echo "Finished !"
Forgot why the space character is treated apart from the others, but ISTR that
the for would not work if $CHR was a space.
Cheers,
Ron.
