问题 I wanted to grant operation access using sudo chmod 777 -R <path> on mac, I double checked the given path, and it's existing and no typos, but I still got chmod: -R: No such file or directory . Any ideas about why I'm getting this error? 回答1: If you look at the synopsis from the man page for chmod you will se the following: SYNOPSIS chmod [OPTION]... MODE[,MODE]... FILE... chmod [OPTION]...

chmod - replicate user permissions to group/world

阅读更多关于 chmod - replicate user permissions to group/world

问题 I have a need to make some folders/files (recursive) have the same permissions as that of the user. So: 0755 -> 0777 0644 -> 0666 How can I do so? Perhaps a little secret command I do know of? If there is no easy way then perhaps I would need to create a loop and test/assign. Ultimately I only need to deal with 3 types: Folders should be 777, most files 666, executables 777. 回答1: find can do the work of finding files with a given permission set and running the smallest possible number of

因为公司的服务器连接是通过xshell公钥和密码连接的，今天在ssh分发秘钥的时候出现了，下面的错误： [root@iZ2ze97cumk8opqm28h8Z .ssh]# ssh-copy-id -i /root/.ssh/id_dsa.pub "root@123.56.82.168 -p 52808" Permission denied (publickey,gssapi-keyex,gssapi-with-mic). 　　于是上网上搜索，网上其他人提供的解决方案为： (1)创建用户: ansible (2)修改sshd_config文件 # vi /etc/ssh/sshd_config //开启以下内容 HostKey /etc/ssh/ssh_host_rsa_key RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys # /etc/init.d/sshd restart （3）权限设置 # mkdir /home/ansible/.ssh # chown -R ansible:ansible /home/ansible # chmod 700 /home/ansible # chmod 700 /home/ansible/.ssh # chmod

How to control file access in Windows?

阅读更多关于 How to control file access in Windows?

问题 Go provides os.Chmod() for setting file and directory permissions. For example, if I want to ensure a file is accessible only to the current user, I can do the following: os.Chmod("somefile.txt", 0600) This works great on Linux but does absolutely nothing on Windows. After digging into the Go source code, I came across its implementation. It seems like S_IWRITE is the only attribute supported. How do I control access to a file or directory on Windows using Go? 回答1: Explanation Windows does
