One Liner Tips : how to kill multiple process with just one line

Posted Under:

Sometime , firefox did crash on me for don’t know what reason.
I think is because of Flash.. It was making some weird sound when tried to play a youtube video.

But even when pressed the close , exit button. (Quit_)
Upon trying to re-launch the firefox ..

something like this appear.

“there is another firefox process already running “

Hence, need to kill all Firefox process one by one.
So come the following …

$ ps xa| grep firefox| grep -v grep | awk '{print $1}' | xargs kill -9

So, after that you can re-launch the firefox again.
As it would no longer complain..

    the above function can be simplified a but further with the following :

    #!/usr/bin/python

def getBM (eng): 
    if eng == 'No rain':
        return "Tiada Hujan"
    if eng == 'Rain':
        return "Hujan"
    if eng == 'fair':
        return "Cerah" 
    if eng == 'Weather Fair':
        return "Cuaca Baik"
    if eng == 'Clear':
        return "Cerah"
    if eng == 'Hazy':
        return "Berjerebu"
    if eng == 'Windy':
        return "Berangin"
    if eng == 'No rain':
        return "Tiada Hujan"
    if eng == 'Cloudy':
        return "Mendung"
    if eng == 'Cloudy over coastal areas':
        return "Mendung di kawasan pantai"
    if eng == 'Cloudy over inland areas':
        return "Mendung di kawasan pedalaman"
    if eng == 'Rain':
        return "Hujan"
    if eng == 'Intermittent rain occasionally moderate':
        return "Hujan sekejap-sekejap kadangkala sederhana"
    if eng == 'Intermittent rain occasionally heavy':
        return "Hujan sekejap-sekejap kadangkala lebat"
    if eng == 'Windspread intermittent rain':
        return "Hujan sekejap-sekejap yang menyeluruh"
    if eng == 'Isolated rain':
        return "Hujan di satu dua tempat"
    if eng == 'Isolated rain over coastal areas':
        return "Hujan di beberapa tempat di kawasan pantai"
    if eng == 'Isolated rain over inland areas':
        return "Hujan di beberapa tempat di kawasan pedalaman"
    if eng == 'Scattered rain':
        return "Hujan curah/sementara di satu dua tempat"
    if eng == 'Scattered rain over coastal areas':
        return "Hujan curah/sementara di kawasan pantai"
    if eng == 'Scattered rain over inland areas':
        return "Hujan curah/sementara di kawasan pedalaman"
    if eng == 'Showers':
        return "Hujan curah"
    if eng == 'Isolated showers':
        return "Hujan curah di satu dua tempat"
    if eng == 'Isolated showers over coastal areas':
        return "Hujan curah di kawasan pantai"
    if eng == 'Isolated showers over inland areas':
        return "Hujan curah di kawasan pedalaman"
    if eng == 'Thunderstorms':
        return "Ribut petir"
    if eng == 'Isolated thunderstorms':
        return "Ribut petir di satu dua tempat"
    if eng == 'Scattered thunderstorms':
        return "Ribut petir di beberapa tempat"
    if eng == 'Widespread thunderstorms':
        return "Ribut petir di kebanyakan tempat"
    else:
        return eng
 
# example usage : 
print "translating 'No rain' = " + getBM("No rain")
print "translating 'No rain' = " + getBM("Scattered thunderstorms")
print "translating 'No rain' = " + getBM("Scattered rain over inland areas")

    hmm. if putting into a file and read from there would be much more better.

    yeah..

    to make it read from a text file and behave exactly as above.

    #!/usr/bin/python

import csv
# to read from a file with list of weather.
reader = csv.reader(open("weather_list.txt", "rb"), delimiter=':', quoting=csv.QUOTE_NONE)
# build up a reference list
kamus = {}
for row in reader:
 english_w=row[0].lstrip(' ').strip(' ')
 bm_w=row[1].lstrip(' ').strip(' ')
 kamus[english_w] = bm_w

# a function to return exactly the same
def getBM (eng) :
 return kamus[eng]
# example usage : 
print getBM ("Isolated showers");
print getBM ("Rain");

    then create text file with the following content.

    [namran@nb-namran Desktop]$ cat weather_list.txt 
Weather Fair:Tiada Hujan
Clear:Cerah
Hazy:Berjerebu
Windy:Berangin
No rain:Tiada Hujan
Cloudy:Mendung
Cloudy over coastal areas:Mendung di kawasan pantai
Cloudy over inland areas:Mendung di kawasan pedalaman
Rain:Hujan
Intermittent rain occasionally moderate:Hujan sekejap-sekejap kadangkala sederhana
Intermittent rain occasionally heavy:Hujan sekejap-sekejap kadangkala lebat
Widespread intermittent rain:Hujan sekejap-sekejap yang menyeluruh
Isolated rain:Hujan di satu dua tempat
Isolated rain over coastal areas:Hujan di beberapa tempat di kawasan pantai
Isolated rain over inland areas:Hujan di beberapa tempat di kawasan pedalaman
Scattered rain:Hujan curah/sementara di satu dua tempat
Scattered rain over coastal areas:Hujan curah/sementara di kawasan pantai
Scattered rain over inland areas:Hujan curah/sementara di kawasan pedalaman
Showers:Hujan curah
Isolated showers:Hujan curah di satu dua tempat
Isolated showers over coastal areas:Hujan curah di kawasan pantai
Isolated showers over inland areas:Hujan curah di kawasan pedalaman
Thunderstorms:Ribut petir
Isolated thunderstorms:Ribut petir di satu dua tempat
Scattered thunderstorms:Ribut petir di beberapa tempat
Widespread thunderstorms:Ribut petir di kebanyakan tempat
