# disk space usage
df -h

# biggest (10) directories in size (MB)
du -mxS / | sort -n | tail -10

# clean package cache
apt-get clean
# or
yum clean

# ext2, ext3 file systems: reduce default 5% capacity of partition reserved to root (to 1%):
tune2fs -m1 /dev/hda1

# delete files older than 10 days and bigger than 5MB under a dir (/tmp for ex):
find  /tmp -mtime +10 -size +5M -exec rm -f {} \; 

# compress unused directory
tar cvfz dir.tar.gz dir

# look at /var/log , set up logrotate if too big
