可以用文本编辑器编辑符号链接吗?-Isitpossibletoeditasymlinkwithatexteditor?

Yes, in Emacs this is possible in dired-mode, specifically wdired (writable dired) mode.

是的，在Emacs中，可以使用dired模式，特别是wdired(可写dired)模式。

Note, dired and wdired both are built-in packages.

注意，dired和wdired都是内置包。

Here's an example...

这里有一个例子……

(BTW: I'm using Smex to give Emacs M-x command search & execute a more ergonomic UI + fuzzy matching)

(顺便说一句:我正在使用Smex进行Emacs M-x命令搜索并执行更符合人体工程学的UI +模糊匹配)

It's possible in principle, but the editor would need to specifically support it, since reading the destination of a symlink requires a special system call: readlink().

原则上是可能的，但是编辑器需要特别支持它，因为读取symlink的目的地需要一个特殊的系统调用:readlink()。

You're unlikely to find any editors that actually do this, since it's not very useful, and conflicts with what most users want the editor to do when asked to open a symlink: open the file that it points to.

您不太可能找到真正做到这一点的编辑器，因为它并不是很有用，并且与大多数用户希望编辑器在打开一个符号链接时要做的事情有冲突:打开它指向的文件。

As per the Storage of symbolic links section in Wikipedia's article Symbolic Links, the symlinks are stored in an inode. This inode is a data structure containing several information about the file in question - as per this thread, the touch command can be used to change some of its values. So, it may not be possible to modify it by using a text editor, due to the problems that @Wyzard mentioned, but it might be modifiable by using some other command-line tools like touch.

根据Wikipedia文章符号链接中符号链接的存储部分，符号链接存储在inode中。这个inode是一个数据结构，其中包含有关该文件的一些信息——根据这个线程，可以使用touch命令来更改它的一些值。因此，由于@Wyzard提到的问题，可能无法使用文本编辑器对其进行修改，但可以使用其他命令行工具(如touch)对其进行修改。

I hope this helps!

我希望这可以帮助!

It's not possible directly, as others have already pointed out, but of course you can write a script for it. Here's one I came up with when I had to change lots of symlinks

这是不可能直接实现的，正如其他人已经指出的那样，但是当然您可以为它编写一个脚本。这是我想到的一个当我需要改变很多符号链接时

#! /bin/bash

tmp=$(mktemp)
trap "rm $tmp" EXIT

while [ ! -z "$1" ]; do
    filename="$1"; shift
    if [ ! -h "$filename" ]; then
        echo "Not a symlink: $filename";
        continue
    fi
    stat -c "%N" "$filename" >> $tmp
done
emacs $tmp

while read filename linkname; do
    ln -sf "$linkname" "$filename"
done <<(sed "s/'\(.*\)' -> '\(.*\)'/\1 \2/" $tmp)

It worked for me, but it's certainly not perfect, so use at your own risk...

它对我起了作用，但肯定不是完美的，所以在你自己的风险使用……
