I have a directory from which i want to delete some stuff.

So id like to see the heavier files.

du -ch will bring too many information, so i was thinking something like

du -ch | sort by size| head

The sort by size part is troubling me

Any thoughts?

Thanks in advance

du -k | sort -n | tail

But this belongs on SU, not StackOverflow

My first thought is that you can't use -h on a du that you're going to sort. Try:

du | sort -rn | head

  • Wouldn't -r sort it reverse order and then you need |head instead of |tail? At least, on Solaris sort -n sorts in accending order – DVK Oct 22 '09 at 13:15

if you want to see "heavier" files, for which i assume they are bigger size files..

du -ch /home |sort -nr|head

I have an (csh) alias "large" which shows the 10 largest files in my current directory:

alias large     "ls -l  \!* |sort -k5 -rn |head -10"

Depending on the version of du, I like the following:

du -ckhs *

It pulls just the sizes of the items (kind of a top-level only type of thing) in the current directory (sizes of files and sizes of child directories (without listing everything in each)).

As chaos said, you can't sort to have things show up correctly with -h, but it at least gives a good quick overview of sizes without going into too much detail.

This rather lengthy function will display a sorted list with human-readable sizes:

dus () { du -bh ${1:+$1/}* |
    awk 'BEGIN {KMG="KMG"} 
        {printf "%s %08.2f %s\t%s\n",
        index(KMG,substr($1,length($1))),
        substr($1,0,length($1)-1),
        substr($1,length($1)),$0}' | 
    sort -r |
    cut -f 2-
}

which you can then pipe through head:

dus | head

It accepts a directory as an argument:

dus /usr/local

Typically I will use du -s * | sort -nr for this, and work my way down into the directories with larger sizes. The -s option makes it display the total for each item instead of recursing.

eg:

bcl@fozzy:~$ du -s * | sort -nr

Personally I find kdirstat to be very useful to figure out where my disk space has gone. It sorts everything by size, and shows a somewhat useful visual 'treemap' that lets you roughly gauge by sight where space is being used.

Use ls -S to sort by file size.
