linux - sudo -H -u git gitosis-init < ~/id_rsa.pub |错误 : no such file or directory

Question

I got this shell script from a blog about how to equip git with gitosis. But i got a "No such file or directory" error after running the script.

[git@209285 ~]$ sudo -H -u git gitosis-init < ~/id_rsa.pub
Traceback (most recent call last):
  File "/usr/local/bin/gitosis-init", line 9, in <module>
    load_entry_point('gitosis==0.2', 'console_scripts', 'gitosis-init')()

    return app.main()

我很困惑，正如man手册所说:

  -H          The -H (HOME) option sets the HOME environment variable to the homedir of the target user (root by default) as specified in passwd(5).  By default, sudo
           does not modify HOME (see set_home and always_set_home in sudoers(5)).

,引自linux手册。

-H 选项只是将 HOME 环境变量设置为 passwd 中指定的目标用户的 homedir。

但是我在/etc/passwd 文件中指定“/home/git”作为 git 用户的 homedir。

apache:x:48:48:Apache:/var/www:/sbin/nologin
git:x:100:101:git version control:/home/git:/bin/bash
duanduan:x:101:500::/home/duanduan:/bin/bash

但为什么我仍然收到这条消息？还是我对手册中描述的理解不正确？

附加评论:

而且似乎之前指定了一个绝对路径。也许，这不是原因。

我猜是因为 ~ 在传递给 sudo 作为参数之前被 bash 扩展了，为什么不尝试为你的公钥文件指定一个绝对路径？
