How do I move a relative symbolic link?
提问by anasdox
I have a lot of relative symbolic links that I want to move to another directory.
我有很多我想移动到另一个目录的相对符号链接。
How can I move symbolic links (those 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）？

You can turn relative paths into full paths using readlink -f foo. So you would do something like:
您可以使用 将相对路径转换为完整路径readlink -f foo。所以你会做这样的事情：
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 -cto convert the absolute paths back into relative paths.
我注意到您希望保持路径相对。在这种情况下，移动链接后，您可以使用symlinks -c将绝对路径转换回相对路径。

This is a perlsolution that preserves relative paths:
这是一个perl保留相对路径的解决方案：
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 "~/bin $ cat mv_ln
#!/bin/bash

help() {
echo 'usage: mv_ln src_ln dest_dir'
echo ' mv_ln --help'
echo
echo ' Move the symbolic link src_ln into dest_dir while'
echo ' keeping it relative'
exit 1
}
[ "" == "--help" ] || [ ! -L "" ] || [ ! -d "" ] && help
set -e # exit on error
orig_link=""
orig_name=$( basename "$orig_link" )
orig_dest=$( readlink -f "$orig_link" )
dest_dir=""
ln -r -s "$orig_dest" "$dest_dir/$orig_name"
rm "$orig_link"
-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;
}

Improving on Christopher Neylan's answer:
改进 Christopher Neylan 的回答：
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

One can use tarto move a folder containing relative symbolic links.
可以tar用来移动包含相对符号链接的文件夹。
For example:
例如：
