Counting file sizes ???

someone_4 — Sat, 25 Aug 2001 17:31:47 GMT

I did an ll looking for the bigest files and I found one that is 2147483647. Now the way I read it this is 1000000000=1000megs so this would be like a file a little bigger then 2 gigs ? Am I right or an I counting wrong?
And is there a way I can run the ll command to come out with megs as output ?

Richard,

Do a du -sk on the file. YOu will get the size in KB and it will be easier for you.

For ex., du -sk file

2046123 file

This means it is of 2 GB.

Hi Richard,

you could do something like
du -kx * |sort -n
The last file/directory would be the biggest size in KB.

If you only want the biggest size in files (in KB)then

ls -al | grep '^-' | sort +4 |tail -1 | awk '{print $5, $9}'

-HTH

Hi Richard,

If you want the size in MB

ls -al | grep '^-' | sort +4 |tail -1 | awk '{print $5/1048576, $9}'

Ofcourse you do lots of formating, and this is not the only way to do it.

2,147,483,647 bytes / 1024 =
2,097,151.999 KB / 1024 =
2,047.999 MB / 1024 =
1.999 GB

So this file is essentially a 2 GB file. You are reading the number and doing the math correctly.

As far as I know there is no option to tell 'll' to put output in MB directly. You have been given some other good ideas though.

By the way, if the file hit this size and didn't grow any more, I would guess that do not have the 'large files' option turned on for this LV.

You can use fsadm to check and to turn on largefiles if you wish. Do a 'man fsadm' for more info.

Hi Richard,

What Pat says is correct, and 1KB = 1024Bytes(not 1000Bytes) so 1GB = 1073741824 Bytes..... and there is no option for ll cmd to tell u size in MB.

Cheers...
Satish.

Hi Richard,

You are right, it's a 2 gigs file.

To calculate directory size in kilobytes :
#du -sk /dir

To calculate size of selective files inkilobytes :

a=`ls -al *.log ? awk '{print $5}'`
result=0
for c in $a
do
result=`expr $result + $c`
done

sizeInKilo=`expr $result \/ 1024`
sizeInMega=`expr $sizeInKilo \/ 1024`
sizeInGiga=`expr $sizeInMega \/ 1024`

echo "Size in KB = $sizeInKilo"
echo "Size in MB = $sizeInMega"
echo "Size in GB = $sizeInGiga"

Hi again ,

in the expr command, you may see a strange signe some how like a V, but it is not :

It is a back slash followed immediately by slash.
