Empty a File Using Linux Command
Today i received an e-mail notification from cpanel that a partition in my server is almost full.
First i checked largest directories / files using this command :
du -h --max-depth=1 /some/pathThen i noticed that they were some log files which took space in my partition 🙂
Sometimes there is occasion where deleting files from Cpanel takes a very long time to finish.
For example because there are too many files under a directory.
In this situation we can use SSH to delete a directory and all files and subdirectories under that directory.
We can use the command below.
But be careful, do not enter wrong path.
You may delete the wrong directory. 🙂

tar xvfz memcache-3.0.8.tgz
cd memcache-3.0.8

./configure
make
make installTake note of the php extensions directory that memcache is installed in.
Mine is: /usr/local/lib/php/extensions/no-debug-non-zts-20020429/
Then add this line to your php.ini
extension="/usr/local/lib/php/extensions/no-debug-non-zts-20020429/memcache.so"
