Convert Filename to Bash-Friendly Filename (with Dashes)

dash_escape_file.sh

#dash escape filename (version 0.1: must be in current working dir)
dashef(){
    filename=`basename $1 | tr "\n" " "`
#    echo "filename is ${filename}" 
    escaped=`echo $1 | tr " " "-" |tr -d "," | tr "_" "-" | tr "(" "-" | tr ")" "-" | tr "+" "-" | perl -pe 's/\-\-\-/\-/g' | perl -pe 's/\-\-/\-/g'` 
    echo "filename is now $escaped"
    mv "${1}" ${escaped}
}

To escape every filename in the current directory: for f in *; do dashef "${f}"; done
