[ ]#   -	quote characters: ' "#   -	control characters: 0-31 (127 is not dealt with---oops)#   -	- or + as the first character## The GNU version of 'tr' is required. Also requires 'sed'.## Script to process a given list of directories recursively# and rename each file to something that is reasonable.## The rules are:## 1. replace each space, [, ], *, ", and ' character in the name with a#    period.# 2. replace each control character 1..31 with a printable character obtained#    by adding 64 to the ascii value. ^A becomes A, ^B becomes B and so on.# 3. replace a - or + occuring at the beginning of the name with a ### 4. if the resulting name has been changed in any way, then# 5.    if a file of the new name already exists, then# 6.            add a . to the new name and goto step 5.# 7. rename the old name to the new name## written by Kaz Kylheku <kaz@cafe.net># March 1996# Vancouver, Canada## requires GNU 'bash', GNU 'tr', and some sort of 'sed' program.## minimal conversion to bash v2 syntax done by Chet Rameyprocessfile(){        new_name="`echo -n $1 | tr '\173\175\052\077\042\047 ' '.......' |                        tr '[\000-\037]' '[\100-\137]' |                        sed -e 's/^-/#/' -e 's/+/#/'`"        if [ "$new_name" != "$1" ] ; then                while [ -e "$new_name" ] ; do                        new_name="${new_name}."                done                echo changing \"$1\" to \"$new_name\" in `pwd`                mv -- "$1" "$new_name"        fi}processdir(){        set -f        local savepwd="$PWD"        if cd "$1" ; then                set +f                for file in * ; do                        set -f                        if [ "$file" != "." ] && [ "$file" != ".." ] ; then                                if [ -L "$file" ] ; then                                        echo "skipping symlink" $file in `pwd`                                elif [ -d "$file" ] ; then                                        processdir "$file"                                elif [ -f "$file" ] ; then                                        processfile "$file"                                fi                        fi                done                cd "$savepwd"        fi}shopt -s nullglob dotglobif [ $# = 0 ] ; then        echo "$0: must specify a list of directories" >&2	echo "$0: usage: $0 directory [directory ...]" >&2	exit 2fiwhile [ $# != 0 ] ; do        processdir "$1"        shiftdoneexit 0
