Linux命令将一个文件复制到多个文件

Is there a one-line command/script to copy one file to many files on Linux?

是否有一行命令/脚本将一个文件复制到Linux上的多个文件？

cp file1 file2 file3

copies the first two files into the third. Is there a way to copy the first file into the rest?

将前两个文件复制到第三个文件中。有没有办法将第一个文件复制到其余文件中？

#1

Does

是否

cp file1 file2 ; cp file1 file3

count as a "one-line command/script"? How about

算作“一行命令/脚本”？怎么样

for file in file2 file3 ; do cp file1 "$file" ; done

？

Or, for a slightly looser sense of "copy":

或者，为了略微宽松的“复制”感：

tee <file1 file2 file3 >/dev/null

#2

for FILE in "file2" "file3"; do cp file1 $FILE; done

#3

You can use shift:

你可以使用shift：

file=$1
shift
for dest in "$@" ; do
    cp -r $file $dest
done

#4

just for fun, if you need a big list of files:

只是为了好玩，如果你需要一个很大的文件列表：

tee <sourcefile.jpg targetfiles{01-50}.jpg >/dev/null- Kelvin Feb 12 at 19:52

tee / dev / null- Kelvin 2月12日19:52

But there's a little typo. Should be:

但是有一点错字。应该：

tee <sourcefile.jpg targetfiles{01..50}.jpg >/dev/null

tee / dev / null

And as mentioned above, that doesn't copy permissions.

如上所述，这不会复制权限。

#5

You can use standard scripting commands for that instead:

您可以使用标准脚本命令：

Bash:

击：

 for i in file2 file3 ; do cp file1 $i ; done

#6

The simplest/quickest solution I can think of is a for loop:

我能想到的最简单/最快的解决方案是for循环：

for target in file2 file3 do; cp file1 "$target"; done

A dirty hack would be the following (I strongly advise against it, and only works in bash anyway):

一个肮脏的黑客将是以下（我强烈建议反对它，无论如何只适用于bash）：

eval 'cp file1 '{file2,file3}';'

#7

Use something like the following. It works on zsh.

使用类似下面的内容。它适用于zsh。

cat file > firstCopy > secondCopy > thirdCopy

cat file> firstCopy> secondCopy> thirdCopy

要么

cat file > {1..100} - for filenames with numbers.

cat file> {1..100} - 用于带数字的文件名。

It's good for small files.

这对小文件很有用。

You should use the cp script mentioned earlier for larger files.

您应该使用前面提到的cp脚本来处理更大的文件。

#8

You can improve/simplify the for approach (answered by @ruakh) of copying by using ranges from bash brace expansion:

您可以使用bash大括号扩展中的范围来改进/简化复制方法（由@ruakh回答）：

for f in file{1..10}; do cp file $f; done

This copies file into file1, file2, ..., file10.

这会将文件复制到file1，file2，...，file10中。

cat file1 | tee file2 | tee file3 | tee file4 | tee file5 >/dev/null

cat file1 | tee file2 | tee file3 | tee file4 | tee file5> / dev / null
