谁能推荐一个安全的解决方案来递归地用下划线替换从给定根目录开始的文件和目录名中的空格?例如:
$ tree
.
|-- a dir
| `-- file with spaces.txt
`-- b dir
|-- another file with spaces.txt
`-- yet another file with spaces.pdf
就变成:
$ tree
.
|-- a_dir
| `-- file_with_spaces.txt
`-- b_dir
|-- another_file_with_spaces.txt
`-- yet_another_file_with_spaces.pdf
当前回答
我在这个脚本周围找到了，它可能很有趣:)
IFS=$'\n';for f in `find .`; do file=$(echo $f | tr [:blank:] '_'); [ -e $f ] && [ ! -e $file ] && mv "$f" $file;done;unset IFS

这个做得更多一些。我用它来重命名我下载的种子文件(没有特殊字符(非ascii)，空格，多个点等)。
#!/usr/bin/perl
&rena(`find . -type d`);
&rena(`find . -type f`);
sub rena
{
($elems)=@_;
@t=split /\n/,$elems;
for $e (@t)
{
$_=$e;
# remove ./ of find
s/^\.\///;
# non ascii transliterate
tr [\200-\377][_];
tr [\000-\40][_];
# special characters we do not want in paths
s/[ \-\,\;\?\+\'\"\!\[\]\(\)\@\#]/_/g;
# multiple dots except for extension
while (/\..*\./)
{
s/\./_/;
}
# only one _ consecutive
s/_+/_/g;
next if ($_ eq $e ) or ("./$_" eq $e);
print "$e -> $_\n";
rename ($e,$_);
}
}
实际上，在perl中不需要使用重命名脚本:
find . -depth -name "*[[:space:]]*" -execdir bash -c 'mv "$1" `echo $1 | sed s/[[:space:]]/_/g`' -- {} \;
用于命名为/files文件夹中的文件
for i in `IFS="";find /files -name *\ *`
do
echo $i
done > /tmp/list
while read line
do
mv "$line" `echo $line | sed 's/ /_/g'`
done < /tmp/list
rm /tmp/list
下面是一个合理的bash脚本解决方案
#!/bin/bash
(
IFS=$'\n'
for y in $(ls $1)
do
mv $1/`echo $y | sed 's/ /\\ /g'` $1/`echo "$y" | sed 's/ /_/g'`
done
)
奈迪姆答案的递归版本。
find . -name "* *" | awk '{ print length, $0 }' | sort -nr -s | cut -d" " -f2- | while read f; do base=$(basename "$f"); newbase="${base// /_}"; mv "$(dirname "$f")/$(basename "$f")" "$(dirname "$f")/$newbase"; done
