This will bring the largest file in the directory. But if the directory has the maximum size then it would list the directory rather than the files.

du -ms * | sort | tail -1

I was getting the below error ,OS is HP unix

$ du -ms * | sort | tail -1
du: illegal option -- m
usage: du [-a|-s] [-kbrx] [-t type] [name ...]

Thanks ,

My OS is an Linux version one, let me check out for the HP-UX.

Try using the following command,

du -a | sort -n | tail -2 | head -1 | cut -f2

In the Directry Give....

ls -ls|sort -nr|head -1

that gives the largest file statistics...

It is working for find the bigger file size in current directory both in HP-UX and in Linux (open Suse). But if there is a bigger sized directory around it will point that.

Hi,
Please find the answer

#!/bin/ksh
calc_size=0
for i in `ls -l|grep "^-"|awk '{print $5"|"$9}'`
do
fname_size=`echo "$i"|awk -F"|" '{print $1}'`
if [ $fname_size -ge $calc_size ];then
calc_size=$fname_size
fname=`echo "$i"|awk -F"|" '{print $2}'`
fi
done
echo "File \"$fname\" is the largest with size $calc_size"

since you said you are working on linux, i don't think so you have korn shell. You execute by changing first line like
#!/bin/sh

Thanks,

with GNU find

find /path -type f -printf "%s:%f\n"|sort -n|tail -1
13

With recent versions of zsh:

ls -fl *(.DOL[1])

Beware: the actual bytes and allocated bytes of file may differ.

14

so write down a little bit code :slight_smile:

#!/bin/zsh

ls -fl *(.DOL[1])
15

How about this
du -a | sort -g

16

may be this is better in look:
du -a | sort -g |tail -2 | cut -f2
