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

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

I am puzzled,as the man manual says that:
-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)).
,which is cited from linux manual.
The -H option just sets the HOME environment variable to the homedir of the target user as specified in passwd.
However i specified "/home/git" as homedir for git user in my /etc/passwd file.
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
But why i still got this message? or was incorrect my comprehension of the description in manual?
Append for comments:
And it seems like before with specifying a absolute path.Maybe, it's not the cause.
sudo -H -u git gitosis-init < /home/git/id_rsa.pub

Answer 1

I guess it is because ~ is expanded by bash before transferring to sudo as a argument, why not try to specify a absolute path for you public key file?
