Symlinks
source: 'How can I symlink a file in Linux? - Stack Overflow'
in the folder you want to link from eg courses/ and data is in /STAGE
REMOVE EXISTING FOLDER
rm -rf foldername
ln -s original course123
ln -s /home/user/webs/scorm_courses/STAGE/x course123
ln -s EXISTING_FILE SYMLINK_FILE
Cron

crontab -ledit crons
crontab -e# m h dom mon dow command
0,10,20,30,40,45,50,55 * * * * wget -q http://www.wordpresssite.org/cron.php > /dev/null && rm cron.php >/dev/null 2>&1Determine total directory/folder file size'
The command du "summarizes disk usage of each FILE, recursively for directories," e.g.,
du -hs /path/to/directory-h is to get the numbers "human readable", e.g. get 140M instead of 143260 (size in KBytes) -s is for summary (otherwise you'll get not only the size of the folder but also for everything in the folder separately)
For a quick view:
du | sort -n
lists all directories with the largest last.
du --max-depth=1 * | sort -n
or, again, avoiding the redundant * :
du --max-depth=1 | sort -n
