[英]Recursively rename files to ASCII Standard
So we have a problem where we need to crawl through hundreds of thousands of images and rename all of them to comply with ASCII standards. 因此,我们遇到了一个问题,我们需要抓取成千上万个图像并将其全部重命名以符合ASCII标准。 After doing a lot of research online, we found this handy piece of code:
在网上进行了大量研究之后,我们发现了以下方便的代码:
mv 'file' $(echo 'file' | sed -e 's/[^A-Za-z0-9._-]/_/g')
sourced from: How to remove invalid characters from filenames 来源: 如何从文件名中删除无效字符
I have tried merging it into a recursive find command, to be run whilst in our main images directory: 我尝试将其合并到递归的find命令中,以便在我们的主图像目录中运行:
find . -print0 | xargs -0 mv $(echo | sed -e 's/[^A-Za-z0-9._-]/_/g')
But i cant seem to get it to run. 但是我似乎无法运行它。 The closest i've gotten, is the above code throwing a lot of "mv: target
filename
Is not a directory" 我得到的最接近的是上面的代码,抛出了很多“ MV:目标
filename
不是目录”
So can anyone help with this ? 那么有人可以帮忙吗?
I guess this would be better: 我想这样会更好:
find . -type f -exec bash -c 'for f do d=${f%/*} b=${f##*/} nb=${b//[^A-Za-z0-9._-]/_}; [[ $b = "$nb" ]] || echo mv "$f" "$d/$nb"; done' _ {} +
find
will find all files ( -type f
), pass them as positional arguments to this Bash snippet: find
将查找所有文件( -type f
),并将它们作为位置参数传递给此Bash代码段:
for f do
d=${f%/*} b=${f##*/} nb=${b//[^A-Za-z0-9._-]/_}
[[ $b = "$nb" ]] || echo mv "$f" "$d/$nb"
done
We split the filename into dirname d
and basename b
. 我们将文件名分为dirname
d
和basename b
。 We use parameter expansions to replace all the unwanted characters with underscores and save that expansion into variable nb
. 我们使用参数扩展将所有不需要的字符替换为下划线,并将该扩展保存到变量
nb
。 We check that the expansions $b
and $nb
are distinct (so as to avoid an error with mv
), and if they are distinct, perform the renaming. 我们检查扩展
$b
和$nb
是否不同(以避免mv
错误),如果它们不同,则执行重命名。
I left echo
so that nothing is actually performed, the commands are only echoed. 我离开了
echo
因此实际上什么也没做,仅回显命令。 Remove the echo
if it looks good. 如果看起来不错,请删除
echo
。
Note that this can overwrite files, eg, files a&b
and a_b
. 请注意,这可能会覆盖文件
a&b
和a_b
。
Put this in a shell script, say fixname.sh: 把它放在一个shell脚本中,说fixname.sh:
#!/bin/sh
dir=$(dirname "$1")
name=$(basename "$1")
newname=$(echo "$name" | sed -e 's/[^A-Za-z0-9._-]/_/g')
if [ "$name" != "$newname" ]; then
if [ ! -e "$newname" ]; then
mv "$1" "$dir/$newname"
else
echo >&2 "$newname already exist for $1"
fi
fi
Then use find like so: 然后像这样使用find:
find . -type f -exec sh fixname.sh {} \;
