If you want to clear contents of a file in unix, you could just delete the file and recreate it. But there are much more simple alternatives. You can use echo method. To empty a file just enter the command below. I use my php_error.log file for example.

echo -n > /home/base/logs/php_error.log

That’s it. Your file is empty now. You can use VI Editor. First, open the file that you want to empty with vi editor. I use my php_error.log file for example.

vi /home/base/logs/php_error.log

On the first line, type “dG” without quotes. It means delete globally on VI Editor. Then quit with “:wq” without quotes of course
