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
find . -depth -name '* *' \
| while IFS= read -r f ; do mv -i "$f" "$(dirname "$f")/$(basename "$f"|tr ' ' _)" ; done
一开始我没有把它弄好，因为我没有想到目录。
其他回答
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
In一样
就像选择的答案一样。
brew install rename
#
cd <your dir>
find . -name "* *" -type d | rename 's/ /_/g' # do the directories first
find . -name "* *" -type f | rename 's/ /_/g'
这是一个(相当冗长的)find -exec解决方案，它将“文件已经存在”警告写入stderr:
function trspace() {
declare dir name bname dname newname replace_char
[ $# -lt 1 -o $# -gt 2 ] && { echo "usage: trspace dir char"; return 1; }
dir="${1}"
replace_char="${2:-_}"
find "${dir}" -xdev -depth -name $'*[ \t\r\n\v\f]*' -exec bash -c '
for ((i=1; i<=$#; i++)); do
name="${@:i:1}"
dname="${name%/*}"
bname="${name##*/}"
newname="${dname}/${bname//[[:space:]]/${0}}"
if [[ -e "${newname}" ]]; then
echo "Warning: file already exists: ${newname}" 1>&2
else
mv "${name}" "${newname}"
fi
done
' "${replace_char}" '{}' +
}
trspace rootdir _
递归版本的一个简单替代方法是逐步增加for循环的范围(n个子级别n次，与每一级别上的子目录数量无关)。即从最外层的目录运行这些。
for f in *; do mv "$f" "${f// /_}"; done
for f in */*; do mv "$f" "${f// /_}"; done
for f in */*/*; do mv "$f" "${f// /_}"; done
要检查/理解正在执行的操作，请在上述步骤前后运行以下操作。
for f in *;do echo $f;done
for f in */*;do echo $f;done
for f in */*/*;do echo $f;done
这个做得更多一些。我用它来重命名我下载的种子文件(没有特殊字符(非ascii)，空格，多个点等)。
#!/usr/bin/perl
&rena(`find . -type d`);
&rena(`find . -type f`);
sub rena
{
($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,$_);
}
}
