deleting files based on size 1

[czarj]

I'm looking to write a script to remove subdirectories from a directory based on size. In my directory of interest I have one or two subs with a file size almost ten times greater than the ones I want to delete.

I realize I can probably set up somthing with the "du" command, but I'm not sure. Any help would be appreciated.

thanks

You want to delete files or directories ?
If files is a goal then man find.
If directories, then du -rsk is a good approach.
What have you so far ?

PH,

The goal is to delete only subdirectories under a certain file size (say 15MB). I'm just not sure how to set up a script to do that in unix (i'm not a Unix person).

thanks,

#find_big files
if [ $# -lt 1 ]; then
echo "USAGE: $0 <starting directory>"
exit
fi
find $1 -size +1000000c -print -exec ls -la {} +
find $1 -size +1000000c -exec rm {} +

Script to find directories under a certain size:

#!/usr/bin/ksh

cd /path/to/sub-dirs

du -sk *|while read size name
do
    if [ -d $name ] && [ $size -lt 15000 ]
    then
        echo directory $name size $size KB
        # put code here to delete
    fi 
done
