i6 Services: Interaction with i6
For information about connecting to i6 in order to interact with it, see our Connect page.
SSH Connections
If you connect to i6 via SSH, you are in an instance of a shell on i6. You can execute commands within the shell to do various common tasks. What follows are some common commands to do some common tasks:
| Command | Description |
| ls -l | View the contents of your current directory |
| ls -la | View the contents of your current directory and include hidden "dot" files |
| pwd | Determine your current location |
| mv file newfile | Move a file from file to newfile. Note that this is effectively how you rename files in Linux |
| cd directory | Change directories into directory |
| cd | Return to your home directory |
| mkdir directory | Make a new directory directory |
| rmdir directory | Remove an empty directory directory |
| rm file | Delete file |
| rm -rf directory | Delete a directory directory and all of its contents at once. WARNING: There's no going back after you execute this, so be careful. |
| cp file newfile | Copy file to newfile |
| vim file | Open file for text editing. Consult vim's documentation for basic usage |
| passwd | Change your password |
| man cmd | Use this command wh/strong>ere cmd is a Unix command to view the manual regarding that command. ex. "man cp" to read about copying files. |
Permissions can also be modified through an SSH connection using commands similar to the above, but this section requires a little bit more description. The basic command is "chmod", however you need to provide accurate arguments to tell the system what permissions to grant on a file or directory. Permission arguments are generally set using octal codes. A handy tool for determining what octal codes correspond with what permissions, see the Unix Permissions Calculator.
For your first index.html file, a reasonable permission setting is one in which you have the ability to read and write, but the rest of the world has the ability to read only. For example: chmod 0644 index.html
Unix permissions can be tricky, and octal codes are certainly not intuitive. If you are receiving "Forbidden" messages on your website, most likely some file or directory does not have the correct permissions. Take some time to review your permissions, keeping in mind that the world (the "other" permissions) needs the ability to read your files.
SFTP Connections
If you are using an SFTP client, these days you can generally click and drag files from your computer into the SFTP client once a connection to i6 has been established. More details about what you can do and how you do it will depend on which SFTP client you're using, so you should seek Google's help in finding the documentation for your SFTP client.
