Python – Fabric – sudo -u

djangofabricpythonsudo

I'm using fabric to launch a command on a remote server.
I'd like to launch this command as a different user (neither the one connected nor root).

def colstat():
  run('python manage.py collectstatic --noinput')

Trying

def colstat():
  sudo('-u www-data python manage.py collectstatic --noinput')

Oviously this won't work because -u will be considered as a command and not an option of sudo

out: /bin/bash: -u : command not found

(www-data is the user which should run the command)
How can I use www-data to run my command from Fabric ?

Judging from the documentation:

sudo('python manage.py collectstatic --noinput', user='www-data')

Linux – How to use sudo to redirect output to a location I don’t have permission to write to?

Your command does not work because the redirection is performed by your shell which does not have the permission to write to /root/test.out. The redirection of the output is not performed by sudo.

There are multiple solutions:

Run a shell with sudo and give the command to it by using the -c option:
```
sudo sh -c 'ls -hal /root/ > /root/test.out'
```
Create a script with your commands and run that script with sudo:
```
#!/bin/sh
ls -hal /root/ > /root/test.out
```
Run sudo ls.sh. See Steve Bennett's answer if you don't want to create a temporary file.

Launch a shell with sudo -s then run your commands:

[nobody@so]$ sudo -s
[root@so]# ls -hal /root/ > /root/test.out
[root@so]# ^D
[nobody@so]$

Use sudo tee (if you have to escape a lot when using the -c option):
```
sudo ls -hal /root/ | sudo tee /root/test.out > /dev/null
```
The redirect to /dev/null is needed to stop tee from outputting to the screen. To append instead of overwriting the output file (>>), use tee -a or tee --append (the last one is specific to GNU coreutils).

Thanks go to Jd, Adam J. Forster and Johnathan for the second, third and fourth solutions.

Bash – sudo echo “something” >> /etc/privilegedFile doesn’t work

Use tee --append or tee -a.

echo 'deb blah ... blah' | sudo tee -a /etc/apt/sources.list

Make sure to avoid quotes inside quotes.

To avoid printing data back to the console, redirect the output to /dev/null.

echo 'deb blah ... blah' | sudo tee -a /etc/apt/sources.list > /dev/null

Remember about the (-a/--append) flag! Just tee works like > and will overwrite your file. tee -a works like >> and will write at the end of the file.
