批量更名脚本

soloforce

一个用来批量改名的脚本，支持通配符，可以指定前缀名和后缀数字的宽度，原有扩展名则保留不变。结束后在home目录会生成一个log文件。
这个脚本对付大量图片改名的时候很好用

刚学bash，小试钝刀，所有代码几乎都是幼稚粗陋的，不免贻笑大方。

# Sample: batren "~/home/user/*.jpg" mypic 3
# This sample command will rename the files(*.jpg) under "~/home/user/" to
# mypic001.jpg, mypic002.jpg ... mypic012.jpg ... mypic789.jpg ... etc.

比较恶心的是目标文件集要用双引号引起来

# batren: A shell for renaming files in batches B-)
#         lolita@linuxsir.cn 2005
# ----------------------------------------------------------------------------
# Usage: batren <original files> <prefix of newfiles> <postfix width>
# ----------------------------------------------------------------------------
# original files: files to be renamed, wildcards like '*' '?'and paths are allowed.
# prefix of newfiles: you may guess its meaning ,right?
# postfix width: the width of numberic-postfix of the new filename
# ----------------------------------------------------------------------------
# Sample: batren "~/home/user/*.jpg" mypic 3
# This sample command will rename the files(*.jpg) under "~/home/user/" to
# mypic001.jpg, mypic002.jpg ... mypic012.jpg ... mypic789.jpg ... etc.

前一阵学FVWM时就想把网上下的图标都用convert 命令改为png格式的，然后用：
convert *.jpg *.png
结果出现一堆*_1.png, *_2.png, faint!
就拿楼主的参照一下，看看怎样改着，谢谢

推荐用rename
