Like normally command append host sudo echo 127.0.0.1 local.host > /etc/hosts, but we’ll get the Permission denied error message.
sudo testparm /etc/samba/smb.conf.master > /etc/samba/smb.conf bash: /etc/samba/smb.conf: Permission denied
Then how to sudo and redirect output to a file?
One solution is to use sh -c option:
sudo sh -c "testparm /etc/samba/smb.conf.master > /etc/samba/smb.conf"
Or you could use a tee command like this:
testparm /etc/samba/smb.conf.master | sudo tee /etc/samba/smb.conf
