Question

rename之类的内容适用于文件，但适用于符号链接目标。

所以，如果我有

link1 -> /usr/share/lib-1.2.2/file1
link2 -> /usr/share/lib-1.2.2/file2

我能做到

rename 1.2.2 2.0.3 link*

并且

link1 -> /usr/share/lib-2.0.3/file1
link2 -> /usr/share/lib-2.0.3/file2

Answer 1

使用此脚本：

#!/bin/sh
from="$1"
to="$2"
shift 2
for i
do
  a=$(readlink "$i") && ln -sf "$(echo $a | sed "s@$from@$to@")" "$i"
done

用法示例：

$ ls -l
total 0
lrwxrwxrwx 1 igor igor 6 Jul 12 18:56 1 -> /bin/1
lrwxrwxrwx 1 igor igor 7 Jul 12 18:56 10 -> /bin/10
lrwxrwxrwx 1 igor igor 6 Jul 12 18:56 2 -> /bin/2
lrwxrwxrwx 1 igor igor 6 Jul 12 18:56 3 -> /bin/3
lrwxrwxrwx 1 igor igor 6 Jul 12 18:56 4 -> /bin/4

lrwxrwxrwx 1 igor igor 10 Jul 12 18:57 4 -> /usr/bin/4
lrwxrwxrwx 1 igor igor 10 Jul 12 18:57 5 -> /usr/bin/5
