统计用户磁盘所占空间

用着中端，显示磁盘空间不足，因此写了这个脚本，统计各个用户所用磁盘空间大小。

将该文件放在179的/home目录下，进行执行，在/home目录下将生成4_25.txt文件。

注：总空间1T, 可以用  “ df "命令统计磁盘总空间大小。

file: x.sh     usage: sudo ./x.sh

#! /bin/sh
tmpfilename=/tmp/4.txt
storefilename=4_25.txt
leftspace=0

rm -f ${tmpfilename} 
rm -f ${storefilename} 

for user in `ls -l | awk '/^d/{print $NF}'`
do
    total=`du --max-depth=0 -s -m ./${user}/  2>/dev/null | awk 'BEGIN{sum = 0;} {sum += $1} END{print sum}'` 
    echo ${user} '        ' ${total} >> ${tmpfilename}
    let "leftspace=${leftspace} + ${total}"
done

((leftspace = 1024 * 1024 - leftspace))

echo leftspace'     '${leftspace} >> ${tmpfilename}


#echo "UNIT:M" > ${storefilename}


sort -k 2 -n -r ${tmpfilename} | awk '{printf "%-20s  %-10s
", $1, $2}' >> ${storefilename}


rm -f ${tmpfilename}

#python plot.py

图形化显示各用户空间的百分比。

注意179以不能自动更新，若要运行该脚本，请放置本地运行。

file: plot.py   usage: ./plot.py

plot.py 与4_25.txt同目录。

#! /usr/bin/python                                                                                                 

import matplotlib.pyplot as plt

labels = []
quants = []

for line in file('4_25.txt'):
    info = line.split()
    labels.append(info[0])
    quants.append(float(info[1]))

plt.figure(1, figsize = (6, 6)) 

def explode(label, target = 'leftspace'):
    if label == target: 
        return 0.1
    else:   
        return 0

expl = map(explode, labels) 

colors = ["pink", "coral", "yellow", "orange"]

plt.pie(quants, explode=expl, colors=colors, labels=labels,
        autopct='%1.1f%%', pctdistance=0.8, shadow=True)

plt.title('179 FULL SPACE 1T', bbox={'facecolor':'0.8', 'pad':5})

plt.savefig('4_25.png')
plt.show()
