如何移动相对符号链接？

I have a lot of relative symbolic links that I want to move to another directory.

我有很多相对符号链接，我想移动到另一个目录。

How can I move symbolic links (ones with a relative PATH) while preserving the right path?

如何在保留正确路径的同时移动符号链接（具有相对路径的链接）？

4 个解决方案

#1

You can turn relative paths into full paths using readlink -f foo. So you would do something like:

您可以使用readlink -f foo将相对路径转换为完整路径。所以你会做类似的事情：

ln -s $(readlink -f $origlink) $newlink
rm $origlink

EDIT:

编辑：

I noticed that you wish to keep the paths relative. In this case, after you move the link, you can use symlinks -c to convert the absolute paths back into relative paths.

我注意到你希望保持相对路径。在这种情况下，移动链接后，可以使用符号链接-c将绝对路径转换回相对路径。

This is a perl solution that preserves relative paths:

这是一个保留相对路径的perl解决方案：

use strictures;
use File::Copy qw(mv);
use Getopt::Long qw(GetOptions);
use Path::Class qw(file);
use autodie qw(:all GetOptions mv);

my $target;
GetOptions('target-directory=s' => \$target);
die "$0 -t target_dir symlink1 symlink2 symlink3\n" unless $target && -d $target;

for (@ARGV) {
    unless (-l $_) {
        warn "$_ is not a symlink\n";
        next;
    }
    my $newlink = file(readlink $_)->relative($target)->stringify;
    unlink $_;
    symlink $newlink, $_;
    mv $_, $target;
}

#3

One can use tar to move a folder containing relative symbolic links.

可以使用tar来移动包含相对符号链接的文件夹。

For example:

例如：

cd folder_to_move/..
tar czvf files.tgz folder_to_move
cd dest_folder/..
tar xzvf /absolute/path/to/folder_to_move/../files.tgz

# If all is fine, clean-up
rm /absolute/path/to/folder_to_move/../files.tgz
rm -rf /absolute/path/to/folder_to_move

help() {

   echo '       mv_ln --help'
   echo
   echo '  Move the symbolic link src_ln into dest_dir while'
   echo '  keeping it relative'
   exit 1
}

[ "$1" == "--help" ] || [ ! -L "$1" ] || [ ! -d "$2" ] && help

set -e # exit on error

orig_link="$1"
orig_name=$( basename    "$orig_link" )
orig_dest=$( readlink -f "$orig_link" )
dest_dir="$2"

ln -r -s "$orig_dest" "$dest_dir/$orig_name"
rm "$orig_link"
