How to find the largest files in the directory tree on Solaris.

cd to start point (is acceptable) and as super user run: ls -ailR | sort -rn +5 | more

Sample output under SuSE Linux:

deathstar:/opt # ls -ailR | sort -rn +5 | more
247704 -rwxr-xr-x  1 root root 18330960 Nov 20  2004 oxpsp1.exe

Here’s a Korn shell script that finds largest files on Solaris:

#! /bin/ksh
# igor@krazyworks.com
#
# Use this script to find the largest files in a particular directory.
#
# Variables:
#      $pathname   name of the dir. which to search for large files

clear

echo "Enter path which to search: c"

read pathname

if [ -z $pathname ]
then
    echo "Error: pathname cannot be null! Exiting..."
    exit
fi

if [ -d $pathname ]
then

clear

echo " "
echo "File Owner    File Size   File Date       File Name"
echo "________________________________________"
echo " "

du -koda "$pathname" | sort -rn | head -50 | awk '{print $2}' | while read file
do
    if [ -f $file ]
    then
        owner=$(ls -als $file | awk '{print $4}')
        bsize=$(ls -als $file | awk '{print $6}')
        (( fsize = bsize / 1024 /1024 ))
        mdate=$(ls -als $file | awk '{print $7" "$8" "$9}')
        fpath=$(ls -als $file | awk '{print $10" "$11" "$12}')

        echo $owner"        "$fsize" Mb     "$mdate"        "$fpath
    fi
done

else

    echo " "
    echo "Error: '$pathname' - no such directory! Exiting..."
    echo " "
    exit
fi

Sample output of the above script on a Solaris 8 box:

File Owner      File Size       File Date               File Name
