Count the size and send notification
Hello,

I want to do something simple,

I want to count the dir size (du -sh directoryname) and then check if
it is over 100GB.
If it is more than 100GB I want to send a notification , if it less than 100GB the script can just stop.

I know how to count with du -sh and how to send an email but I dont know how to compare with 100GB, any help?

thank you.

try and modify this:
Quote:
#!/bin/bash

for a in "$(du -s $1)"
do
spc=$(echo $a|cut -d" " -f1)
if [ $spc -gt 100000 ]
then
echo "alert on $1, the space is $spc"|mail wyw@wyw.world -s "Alert space"
fi
done
pass a directory as argument.
adjust the max value when needed

to get the file size in number(GB)
Code:
stat -c %s infile | awk '{print $1/(1024**3)}'

The output from du -sk is in 1024 byte blocks.

100 Gb = (100 x 1024 x 1024 x 1024) bytes
Which is the same as (100 x 1024 x 1024) blocks of size 1024 bytes. i.e. 104857600 1024-byte blocks.

Code:
dir="directoryname"
blocks=$(du -sk "${dir}" | awk '{print $1')
if [ $blocks -gt 104857600 ]
then
       echo "Directory larger than 100 Mb: ${dir}"
fi

@pokerino Your units are incorrect.
