Counting Inodes and Disk Usage

This script will grab your current directory and measure every directory inside it and write the Disk/Inode usage to a file named "usage". This version is useful for cronjobs or for when you don't need to see the output until the script is finished.

Counting Total Inodes

When all you need is a count and don't care about where the files are located at:

$ find ~webuser/ | wc -l
1231

Or if all you care about is the total disk space being used by a user and don't care where the usage is:

$ du -sh ~webuser/

Organizing Inodes and Disk Usage

This script will search through the current directory and build a file usage list for you. It is a little ugly and breaks down using KB but it gets the job done nicely. Script as follows:

IFS=$'\012';
 for d in `find . -type d`;
 do s=$(ls -AlF $d | grep -v / | awk '{ $5 = $5/1024; sum += $5; } END \
 { print sum}') c=$(ls -AF $d|wc -l) ;
 printf "%-20s" ${c} ${s}KB ${d} >>usage; printf "\n">>usage; done

The output looks like:

$ head usage 
15                  4.59473KB           .                   
0                   0KB                 ./bt                
0                   0KB                 ./test_html      
11                  115.152KB           ./public_html       
31                  6184.81KB           ./public_html/images/  
3                   0.0458984KB         ./public_html/images/icons
13                  357.815KB           ./public_html/images/logos
...

This variation does the same thing, only it outputs the data to the screen as it is going into the file using the tee command. This would be more ideal for when you want to watch the search results instead of waiting for the script to finish to see the results.

IFS=$'\012';
 for d in `find . -type d`;
 do s=$(ls -AlF $d | grep -v / | awk '{ $5 = $5/1024; sum += $5; } END \
 { print sum}') c=$(ls -AF $d|wc -l) ;
 printf "%-20s" ${c} ${s}KB ${d}; printf "\n"| tee -a usage; done

Scripts for finding disk usage can be written in numerous ways. This are quick scripts I have whiped out for purposes of demonstration.
