The title says it all. What command I need to run from a terminal to find my user ID (UID)?
I have a fresh install of Ubuntu 12.04.1 LTS an a number of servers.
I have not added any cron jobs or edited my crontab on those servers, however, at around the same time for each machine, I get a 75% CPU spike and the following info in my syslog at the time of the spike:
CRON[8380]: (CRON) info (No MTA installed, discarding output)
I have mono-complete installed and am running a service stack webserver.
What is the best way for me to stop this from happening? I would like to be able to remove the CPU spike.
This question may sound a bit stupid, but I can not really see the difference between redirection and pipes.
Redirection is used to redirect the stdout/stdin/stderr, e.g. ls > log.txt.
Pipes are used to give the output of a command as input to another command, e.g. ls | grep file.txt.
But why are there two operators for the same thing?
Why not just write ls > grep to pass the output through, isn't this just a kind of redirection also? What I am missing?
I'd like to use the adduser command to add a user (with disabled password) via a shell script.
By default, adduser prompts you for various values (e.g., Full Name). Is there any way to submit these values via command line? Or will I need to useradd instead?
Are there any configuration options for the Unity desktop?
There are multiple valid answers for this question spanning over several versions of Ubuntu. For your convenience an index of each below (How can I tell which Ubuntu release I'm using?):
