Linux was designed to allow more than one user to have access to the system at the same time.
In order for this multiuser design to work properly, there needs to be a method to protect users from each other. Permissions are the “rights” to act on a file or directory. The first ten characters show the access permissions.
However, you should include at least the user’s name (for this example the user name is cjones) and of course a [email protected]:~# adduser cjones Adding user `cjones' ... Adding new user `cjones' (1001) with group `cjones' ... [Y/n] Y It is important to note that security should always be taken very seriously.
In this example, the file owner has read and write permissions only.
The next three characters (r–) are the permissions for the members of the same group as the file owner (which in this example is read only).
However, if you’d like to use multiple user accounts with Bash, you can switch between them while inside a Bash shell.
If you are new to Linux/Unix, then the concept of permissions may be confusing.
