在一个目录中有多个以fgh开头的文件,例如:
fghfilea
fghfileb
fghfilec
我想将它们全部重命名为以前缀jkl开头。是否有一个单独的命令来执行该操作,而不是逐个重命名每个文件?

当前回答
在文件列表上运行sed表达式的通用脚本(将sed解决方案与重命名解决方案结合在一起):
#!/bin/sh
e=$1
shift
for f in $*; do
fNew=$(echo "$f" | sed "$e")
mv "$f" "$fNew";
done
通过向脚本传递一个sed表达式来调用,然后是任何文件列表,就像rename的一个版本:
script.sh 's/^fgh/jkl/' fgh*
其他回答
我建议使用我自己的脚本,它可以解决这个问题。它还有更改文件名编码的选项,以及将组合符号转换为预组合字符的选项,这是我从Mac上复制文件时经常遇到的问题。

使用StringSolver工具(windows & Linux bash),通过示例处理:
filter fghfilea ok fghreport ok notfghfile notok; mv --all --filter fghfilea jklfilea
它首先根据示例计算一个过滤器,其中输入是文件名和输出(ok和notok,任意字符串)。如果filter有选项——auto或者在这个命令之后单独被调用,它会创建一个文件夹ok和一个文件夹notok,并分别将文件推送到它们。
然后使用过滤器,mv命令是一个半自动的移动,使用修饰符——auto变成自动的。使用前面的过滤器——filter,它找到了从fghfilea到jklfilea的映射,然后将其应用于所有过滤过的文件。
其他单行解决方案
做同样事情的其他等效方法(每一行都是等效的),所以你可以选择你最喜欢的方法。
filter fghfilea ok fghreport ok notfghfile notok; mv --filter fghfilea jklfilea; mv
filter fghfilea ok fghreport ok notfghfile notok; auto --all --filter fghfilea "mv fghfilea jklfilea"
# Even better, automatically infers the file name
filter fghfilea ok fghreport ok notfghfile notok; auto --all --filter "mv fghfilea jklfilea"
多步骤的解决方案
要仔细查看命令是否执行良好,您可以键入以下命令:
filter fghfilea ok
filter fghfileb ok
filter fghfileb notok
当你确信过滤效果不错时,执行第一步:
mv fghfilea jklfilea
如果你想测试,并使用前面的筛选器,输入:
mv --test --filter
如果转换不是你想要的(例如,即使用mv——解释你看到的东西是错误的),你可以输入mv——clear重新启动移动文件,或添加更多的例子mv input1 input2,其中input1和input2是其他例子
当你有信心的时候,就打字
mv --filter
瞧!所有重命名都是使用筛选器完成的。
免责声明:我是这篇论文的合著者。可能很快还会有bash生成功能。
这是如何使用sed和mv一起执行重命名:
for f in fgh*; do mv "$f" $(echo "$f" | sed 's/^fgh/jkl/g'); done
根据下面的评论,如果文件名中有空格,则可能需要在返回文件名的子函数周围加上引号,以便将文件移动到:
for f in fgh*; do mv "$f" "$(echo $f | sed 's/^fgh/jkl/g')"; done
(在我的Mac上)用Ruby做这个要容易得多。下面是两个例子:
# for your fgh example. renames all files from "fgh..." to "jkl..."
files = Dir['fgh*']
files.each do |f|
f2 = f.gsub('fgh', 'jkl')
system("mv #{f} #{f2}")
end
# renames all files in directory from "021roman.rb" to "021_roman.rb"
files = Dir['*rb'].select {|f| f =~ /^[0-9]{3}[a-zA-Z]+/}
files.each do |f|
f1 = f.clone
f2 = f.insert(3, '_')
system("mv #{f1} #{f2}")
end
这里有一个使用命令行Groovy的方法:
groovy -e 'new File(".").eachFileMatch(~/fgh.*/) {it.renameTo(it.name.replaceFirst("fgh", "jkl"))}'
