我需要更改一批文件的分辨率，有400多个，用下面的shell来做，
for i in *; do convert $i -resize 64x64 $i; done  
不少文件名可能都有空格，结果只能更改几个文件后命令就僵死了。
convert: missing an image filename `X..png'.
convert: unable to open image `CD': No such file or directory.
convert: unable to open image `ROM.png': No such file or directory.
convert: unable to open file `ROM.png'.
convert: unable to open image `CD': No such file or directory.
convert: missing an image filename `ROM.png'.
