Have the following function in fabric for adding user accounts. ~/scripts #fab -l ``` Python source code Available commands: OS_TYPE adduser_createcmd Create command line for adding user adduser_getinfo Prompts for user input for adding user go The main launcher for adding user ``` The tasks ``` @task @runs_once def go(): """ The main launcher for adding user """ user, uid, comment, group, Group, shell = adduser_getinfo() execute(adduser_createcmd(user, uid, comment, group, Group, shell)) @task @runs_once def adduser_getinfo (): """ Prompts for user input for adding user """ with settings(warn_only=True): df_user = "test" df_uid = "6666" df_comment = "Test User" df_group = "1936" df_Group = "sshusers" df_shell = "/bin/bash" #read user input or use default values user = raw_input ("Enter Username [%s]:" %df_user) or df_user uid = raw_input ("Enter UID # [%s]:" %df_uid) or df_uid comment = raw_input ("Enter comments [%s]:" %df_comment) or df_comment group = raw_input ("Enter main group…

Accepted Answer

You should change the line :

```
 execute(adduser_createcmd(user, uid, comment, group, Group, shell))
```

to :

```
 execute(adduser_createcmd, user, uid, comment, group, Group, shell)
```

The first line tells Python to execute the `adduser_createcmd` function with the arguments `(user, uid, comment, group, Group, shell)`and pass the result to the `execute` function. However, Python is not able to execute the `adduser_createcmd` as it is a Fabric task which should be executed on a remote host by the Fabric runtime.

The second line passes as argument the function `adduser_createcmd` and the arguments `(user, uid, comment, group, Group, shell)` to the `execute` function. The Fabric runtime will run the adduser_createcmd function on the remote hosts you specified, propagating the arguments.
