Sometimes it’s good to know which kind of Debian version you are running on your system. This small article shows you how to check for the version.
Sometimes you have lots of processes running on your Linux system and you want to kill them all. But you don’t want to spend too much time on killing each process by their process id. A good way to handle with this problem is to combine ps, with grep and awk:
ps -lax | grep "MY SEARCH PATTERN"| awk '{print $3}' | xargs kill -9
In this case I am getting the whole process list, then I search for processes which contain MY SEARCH PATTERN. After this I am getting the 3rd column, because there is the process ID. After that we kill ‘em all!
By default the logging for the cron demon is not active in Debian Linux. To activate it, please open the file /etc/rsyslog.conf via
vi /etc/rsyslog.conf
and uncomment the line
# cron.* /var/log/cron.log
After that you need to restart rsyslog via
/etc/init.d/rsyslog restart
and you will find the cron logs in /var/log/cron.log
I got the following errors when I ran
locale
on my Debian installation:
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
To fix this I executed
localedef -i en_US -c -f UTF-8 en_US.UTF-8
to redefine my locale-settings.
