Linux How To Empty Or Truncate A File
It is easy to truncate or empty a file from the command line on Linux
You can echo an empty string to the file that you want to truncate like this.
echo > test.log
You can also just use the redirection operator by itself like this.
There also exists a truncate command which allows you to truncate a file to whatever size you want. In this case we are setting the size to zero which will effectively empty the file.
truncate -s 0 test.log
