Unix Script cannot copy filename with brackets

i am trying to write a bash script to backup recent files from a directory.

it works well, except that it does not copy files whose names have brackets.

(i.e. banner[1].jpg)

any advice on how i might be able to do this, or on code that would find and rename such files before i run my copy script?

thanks!

my script
____
#!/bin/sh

# this script will backup all files from the last month to a secondary location


date=$(date "+%m-%d-%y")
# mkdir backup_$date
cd /Volumes/192.168.1.15/apps/GoldMine/Mailbox/Attach/
find . -mtime 1 | \
while read file

do

#avoiding pesky trivial output
if [ "$file" = "." ]
then
else
echo "$file"
cp "$file" /Volumes/192.168.1.108/ScriptTest/backup_$date/"$file"
fi
done

solved my own problem using the tr command

# this script will backup all files from the last month to a secondary location



date=$(date "+%m-%d-%y")

mkdir backup_$date

cd /Volumes/192.168.1.15/apps/GoldMine/Mailbox/Attach/

find . -mtime 1 | \
while read file

do
# file2 holds the filename without brackets
echo "$file" > temp.txt
file2=$(tr -d [] < temp.txt)

#remove bracket characters in target so copy operation will not fail
if [ "$file" != "$file2" ]
then cp "$file" /Volumes/192.168.1.108/ScriptTest/backup_$date/"$file2"


#do nothing to the directory you are in
elif [ "$file" = "." ]
then echo backup started on `date`

#copy an entire directory
elif [ -d "$file" ]
then cp -r "$file" /Volumes/192.168.1.108/ScriptTest/backup_$date/"$file"


else

cp "$file" /Volumes/192.168.1.108/ScriptTest/backup_$date/"$file"

fi
done
