My Script is,
Code:
size='du -sh'
$size
size1='30M'
if [ $size -gt $size1 ]
then
  echo "size greater"
else
  echo "size smaller"
fi

its showing

Code:
36M     .
size.sh: line 4: [: too many arguments
size smaller

Error

try this..

Code:
 
size=`du -sh`
size=`echo $size | sed 's/.$//'`
size1='30'
if [ $size -gt $size1 ]
then
echo "size greater"
else
echo "size smaller"
fi

@shaal89

you are using -h option, if your directory size goes to 1 to 29 GB, then the above command will fail. Because you are checking it for MB and we are removing the human readable format in the end ( M or G or K )
