How to replace spaces in file names using a bash script
提问by armandino
Can anyone recommend a safe solution to recursively replace spaces with underscores in file and directory names starting from a given root directory? For example:
任何人都可以推荐一种安全的解决方案，从给定的根目录开始，在文件和目录名称中递归地用下划线替换空格吗？例如：
$ tree
.
|-- a dir
| `-- file with spaces.txt
`-- b dir
|-- another file with spaces.txt
`-- yet another file with spaces.pdf
becomes:
变成：
$ tree
.
|-- a_dir
| `-- file_with_spaces.txt
`-- b_dir
|-- another_file_with_spaces.txt
`-- yet_another_file_with_spaces.pdf

Use rename(aka prename) which is a Perl script which may be on your system already. Do it in two steps:
使用rename(aka prename) 这是一个 Perl 脚本，它可能已经在您的系统上。分两步做：
find -name "* *" -type d | rename 's/ /_/g' # do the directories first
find -name "* *" -type f | rename 's/ /_/g'
Based on Jürgen'sanswer and able to handle multiple layers of files and directories in a single bound using the "Revision 1.5 1998/12/18 16:16:31 rmb1" version of /usr/bin/rename(a Perl script):
基于Jürgen 的回答，并且能够使用“Revision 1.5 1998/12/18 16:16:31 rmb1”版本/usr/bin/rename（Perl 脚本）在单个范围内处理多层文件和目录：
find /tmp/ -depth -name "* *" -execdir rename 's/ /_/g' "{}" \;
回答by Michael Krelin - hacker
find . -depth -name '* *' \
| while IFS= read -r f ; do mv -i "$f" "$(dirname "$f")/$(basename "$f"|tr ' ' _)" ; done
failed to get it right at first, because I didn't think of directories.
一开始没做好，因为我没有想到目录。

A find/renamesolution. renameis part of util-linux.
一个查找/重命名的解决方案。重命名是 util-linux 的一部分。
You need to descend depth first, because a whitespace filename can be part of a whitespace directory:
您需要先降低深度，因为空白文件名可以是空白目录的一部分：
find /tmp/ -depth -name "* *" -execdir rename " " "_" "{}" ";"

Here's a (quite verbose) find -exec solution which writes "file already exists" warnings to stderr:
这是一个（相当冗长的） find -exec 解决方案，它将“文件已存在”警告写入标准错误：
function trspace() {
declare dir name bname dname newname replace_char
[ $# -lt 1 -o $# -gt 2 ] && { echo "usage: trspace dir char"; return 1; }
dir=""
replace_char="${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}/${bname//[[:space:]]/#!/bin/bash
(
IFS=$'\n'
for y in $(ls )
do
mv /`echo $y | sed 's/ /\ /g'` /`echo "$y" | sed 's/ /_/g'`
done
)
}"
if [[ -e "${newname}" ]]; then
echo "Warning: file already exists: ${newname}" 1>&2
else
mv "${name}" "${newname}"
fi
done
' "${replace_char}" '{}' +
}
trspace rootdir _

Here's a reasonably sized bash script solution
这是一个合理大小的 bash 脚本解决方案
#!/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 [0-7][_];
tr [ IFS=$'\n';for f in `find .`; do file=$(echo $f | tr [:blank:] '_'); [ -e $f ] && [ ! -e $file ] && mv "$f" $file;done;unset IFS
0-][_];
# 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,$_);
}
}

This one does a little bit more. I use it to rename my downloaded torrents (no special characters (non-ASCII), spaces, multiple dots, etc.).
这个做的多一点。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）。
detox -r <folder>

This only finds files inside the current directory and renames them. I have this aliased.
这只会在当前目录中查找文件并重命名它们。我有这个别名。
find ./ -name "* *" -type f -d 1 | perl -ple '$file = $_; $file =~ s/\s+/_/g; rename($_, $file);
find ./ -name "* *" -type f -d 1 | perl -ple '$file = $_; $file =~ s/\s+/_/g; rename($_, $file);
