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
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。

其他回答
有几种方法,但使用rename可能是最简单的。
使用一个版本的rename (Perl的rename):
rename 's/^fgh/jkl/' fgh*
使用另一个版本的rename(与Judy2K的答案相同):
rename fgh jkl fgh*
您应该检查您的平台的手册页,以确定上述哪一种方法适用。
rename fgh jkl fgh*
这是find + sed + xargs解决方案的扩展版本。
原来的解是这个和这个。
要求:搜索,修剪,正则表达式,重命名
我想重命名多个文件夹中的多个文件。 一些文件夹应该被删除。 我在cygwin上,不能让perl重命名工作,这是最流行的解决方案所需要的(我假设它很慢,因为它似乎没有修剪选项?)
解决方案
使用find可以有效地获取文件(带有修剪),并提供许多自定义选项。 使用sed替换正则表达式。 使用xargs将结果汇集到最终命令中。
例1:重命名*.js文件,忽略node_modules
这个示例查找文件并对找到的文件和重命名的文件进行回显。出于安全考虑,它目前没有移动任何东西。你需要用mv代替echo。
set -x # stop on error
set -e # verbose mode (echo all commands)
find "." -type f -not \( -path "**/node_modules/**" -prune \) -name "*.js" |
sed -nE "s/(.*)\/my(.*)/& \1\/YOUR\2/p" |
xargs -n 2 echo # echo first (replace with `mv` later)
上面的脚本转换为:
./x/y/my-abc.js
到这个:
./x/y/YOUR-abc.js
溶液分解
find "." -type f -not \( -path "**/node_modules/**" -prune \) -name "*.js" Searches for files (-type f). The -not part excludes (and, importantly does not traverse!) the (notoriously ginormous) node_modules folder. File name must match "*.js". You can add more include and exclude clauses. Refs: This post discusses recursive file finding alternatives. This post discusses aspects of pruning and excluding. man find sed -nE "s/(.*)\/my\-(.*\.js)/& \1\/YOUR-\2/p" NOTE: sed always takes some getting used to. -E enables "extended" (i.e. more modern) regex syntax. -n is used in combination with the trailing /p flag: -n hides all results, while /p will print only matching results. This way, we only see/move files that need changing, and ignore all others. Replacement regex with sed (and other regex tools) is always of the format: s/regex/replacement/FLAGS In replacement, the & represents the matched input string. This will be the first argument to mv. Refs: linux regex tutorial man sed xargs -n 2 echo Run the command echo with (the first two strings of) the replaced string. Refs: man xargs
好运!
您也可以使用下面的脚本。它很容易在终端上运行…
//一次重命名多个文件
for file in FILE_NAME*
do
mv -i "${file}" "${file/FILE_NAME/RENAMED_FILE_NAME}"
done
例子:-
for file in hello*
do
mv -i "${file}" "${file/hello/JAISHREE}"
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
