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 243985 -rwxr-xr-x 1 root root 15516048 Nov 20 2004 oxpsp2.exe 91951 -r--r--r-- 1 root root 14886200 Apr 13 2005 libsvx645li.so 91952 -r--r--r-- 1 root root 13648358 Apr 13 2005 libsw645li.so 96205 -rwxr-xr-x 1 root root 12957520 Sep 13 2004 thunderbird-bin 91931 -r--r--r-- 1 root root 10539873 Apr 13 2005 libsc645li.so 974337 -rwxr-xr-x 1 root root 9771152 Nov 7 2004 firefox-bin 447 -rwxr-xr-x 1 root root 9004320 Sep 26 14:02 libgklayout.so 91890 -r--r--r-- 1 root root 8576819 Apr 13 2005 libicudata.so.22.0 201928 -rwxr-xr-x 1 root root 6649080 Apr 7 2004 libgucharmap.so.3.0.3
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 _____________________________________________ nbar 93 Mb Nov 21 08:14 /opt/SUNWnbaro/var/nbar/nbjobs.MYI nbar 60 Mb Nov 21 08:06 /opt/SUNWnbaro/var/nbar/nbjobfs.MYD nbar 59 Mb Nov 21 05:20 /opt/SUNWnbaro/var/nbar/nbwindows.MYI nbar 50 Mb Nov 21 08:14 /opt/SUNWnbaro/var/nbar/nbjobs.MYD nbar 43 Mb Nov 20 08:16 /opt/SUNWnbaro/var/nbar/nbwindows.MYD nbar 31 Mb Nov 21 08:06 /opt/SUNWnbaro/var/nbar/nbjobfs.MYI nbar 13 Mb Nov 21 05:20 /opt/SUNWnbaro/var/nbar/nbschedules.MYI root 13 Mb May 6 2001 /opt/VRTSob/jre/lib/rt.jar root 12 Mb May 11 2001 /opt/VRTSvcs/gui/jre/lib/rt.jar root 12 Mb Aug 7 2003 /opt/QLogic_Corporation/SANblade_Control_FX/scfx
