What's New in R82
A good tool to find what is taking up your disk space is "treesize". You can add it to your gateway by following the instructions below:
1. vi /bin/treesize
2. Paste everything between the hashes below (including the last line with ' on it):
############################
du -k --max-depth=1 | sort -nr | awk '
BEGIN {
split("KB,MB,GB,TB", Units, ",");
}
{
u = 1;
while ($1 >= 1024) {
$1 = $1 / 1024;
u += 1
}
$1 = sprintf("%.1f %s", $1, Units[u]);
print $0;
}
'
############################
3. Save and exit vi:
Esc, followed by ":wq"
4. Change permissions so you can run treesize:
chmod 777 /bin/treesize
5. Run the tool, eg:
cd /var/log
treesize
