Thread: Python running as a process in Ubuntu?


hi, apologize if ridiculous question, but:

when running:

ps ax | grep "python", see....

1632 ? s 0:00 python /usr/share/system-config-printer/applet.py
1873 ? s 0:00 /usr/bin/python /usr/sbin/aptd
---------------------------------------------------------------

simple question, not problem, why python running process in background? essential os? appears if printer dependent on it? link cups? know looks obvious, little enlightenment help. process runs after reboot. in advance.

the python interpreter running programs listed after name python, in first case it's applet related printer configuration, , in second case, it's aptd (a part of package management system, apt http://en.wikipedia.org/wiki/advanced_packaging_tool).

critical thing python language, , python interpreter program executes code written in python. many linux programs , system tools written in python , executed using command: "python [insert path program]", or, if programmer had reason so, may specify exact location of python interpreter using "/usr/bin/python [program path]". in ubuntu these equivalent. show in ps "python [program path]" or "/usr/bin/python [program path]". putting "python" or "/usr/bin/python" in command tells os interpreter use. there lots of interpreted languages, bash, ksh, tcl, , more. run tcl code may use command "tcl [program name]" or "/usr/bin/tcl [program name]".

in case of 2 programs seeing, not think malicious , restarted system after reboot.

if see program don't can terminate using pid (process identification) along command "kill". example, if have firefox running , freezes, search using ps , issue command "kill [insert firefox pid]" end process. type "man kill" terminal more information. useful 1 "killall", watch out 1 terminates processes based on name (eg "killall firefox") , can terminate stuff make have hard reboot (or issue reisub command...google it).

Thread: Can not create raid array: mdadm: no raid-devices specified.

hello! i'm trying setup software raid on server, fail @ first step: code: root@sandnabba:/root# mdadm -c /dev/md0 -c512 -l5 /dev/sdc1 /dev/sdd1 /dev/sde1 mdadm: no raid-devices specified. what doing wrong!? are sure -c equivalent --create? also, think need space after -c , -l options, value shouldn't command, or should have = between. @ man pages mdadm , double check spelling.

hi, if developing platform independent software in linux using gtk+/gtkmm , you've managed cross compile windows, guide you. i'm posting because after researching topic myself, encountered many posts people have abandoned gtk+/gtkmm wxwidgets because of gtks ugly default appearance in windows/wine. gtk+ themeable in windows/wine gnome. have set correctly . . . here's how. guide gtkmm gtk+ similar. (1) firstly, download , install gtkmm windows using wine. (you have if have cross compiled app windows) https://live.gnome.org/gtkmm/mswindows (2) run these commands create proper directory structure. (substitute 'proj' whatever project called) mkdir ~/proj mkdir ~/proj/bin mkdir ~/proj/etc mkdir ~/proj/etc/gtk-2.0 mkdir ~/proj/lib mkdir ~/proj/lib/gtk-2.0 mkdir ~/proj/lib/gtk-2.0/2.10.0 mkdir ~/proj/lib/gtk-2.0/2.10.0/engines mkdir ~/proj/share mkdir ~/proj/share/themes (3) move directory gtkmm installed (probably ~/.wine/drive
