sub-directory size

Dear Sirs,

What is command or script to find sub-directory or directory size in MegaByte (MB) or GB ?

Thanks in advance.

$ du -sk subdir

This will give you the size in Kb. Multiply this by 1024 for Mb.

The 'du' command has these options.

Umm....Actually you would divide the output of 'du -sk' by 1024 to get the size in MB. Then divide again by 1024 to get GB.

If you multiplied the output by 1024, you'd get the size in BYTES.

Size in KB
# du -ks /somedir
1234567890 somedir

Size in MB
# echo 1234567890/1024|bc -l
1205632.70507812500000000000

Size in GB
# echo 1205632.705078125/1024|bc -l
1177.37568855285644531250

Hello Shiv,

Size in KB
echo `du -ks | awk '{print $1}'`

Size in MB
echo `du -ks | awk '{print $1}'`/1024|bc -l

Size in GB
echo `du -ks | awk '{print $1}'`/1024/1024|bc -l

Hi David

We have to devide by 1024 to get size in MB
