如何导出每日磁盘空间使用情况？

Question

I am new to scripting.

Is it possible to export the disk space usage of a linux server to an excel shell(.csv) sheet daily ? If so, what will be the scripting for that?

Answer 1

Using shell sctript you can write it as below. And then you can schedule your script by using crontabs.

Script:-

#!/bin/bash

DDATE=$(date '+%Y-%m-%d')
{
TIME=$(date)
DISK=$(df -h)

echo $DDATE

cat <<-EOF

>>>>Disk space<<<<
$DISK
EOF

wait

} > /tmp/output.csv
exit;

Answer 2

Use awk to parse df result:

Assuming ; is your csv separator, then:

df -h | awk 'FNR == 2 {print $2";"$3";"$4}'

gives:

24G;5.4G;18G

In a full script with the date:

#!/bin/bash

SEPARATOR=","
SIZES=`df -h | awk -v SEP="$SEPARATOR" 'FNR == 2 {print SEP$2SEP$3SEP$4}'`
echo `date +%Z-%Y-%m-%d_%H-%M-%S`"$SIZES" >> test.csv

Answer 3

如果您需要更高级的每日统计数据和历史记录，可以在crontab中使用诸如http://diskreport.net之类的工具。
