Linux辅助函数：如何使用sftp创建一个新用户

# usage: create_sftp_user
function create_sftp_user() {
# create user
sudo adduser --disabled-password --gecos "" $1
# prevent ssh login & assign SFTP group
sudo usermod -g sftpaccess $1
sudo usermod -s /bin/nologin $1
# chroot user (so they only see their directory after login)
sudo chown root:$1 /home/$1
sudo chmod 755 /home/$1
sudo mkdir /home/$1/data
sudo chown $1:$1 /home/$1/data
sudo chmod 755 /home/$1/data
sudo mkdir /home/$1/.ssh
sudo chown $1:$1 /home/$1/.ssh
sudo chmod 755 /home/$1/.ssh
sudo ssh-keygen -f /home/$1/.ssh/id_rsa -C "$1@client-data" -N ""
sudo chown $1:$1 /home/$1/.ssh/id_rsa
sudo chmod 600 /home/$1/.ssh/id_rsa
sudo chown $1:$1 /home/$1/.ssh/id_rsa.pub
sudo chmod 644 /home/$1/.ssh/id_rsa.pub
sudo touch /home/$1/.ssh/authorized_keys
sudo chown $1:$1 /home/$1/.ssh/authorized_keys
sudo chmod 666 /home/$1/.ssh/authorized_keys
sudo cat /home/$1/.ssh/id_rsa.pub >> /home/$1/.ssh/authorized_keys
sudo chmod 644 /home/$1/.ssh/authorized_keys
