erase file

I have a file that always generated in the system eg. /tmp/log.txt , it is generated by the application program , but this file should not be present in the system otherwise there are some program problem , I want to erase this file once the program has generate it , as I know , it can link to /dev/null , could suggest how to make it

I use the function , it is OK to link the file , but the /tmp/log.txt is exist , even the file can't be update but I really don't want the file exist in the system , how can I make the file don't appear in the system ( even the file size is 0 ) ? thx

/tmp/log.txt -- > /dev/null

Well, to erase the file, you'd do an rm /tmp/log.txt

You could do this as a cronjob, or via a shell script that is in cron that checks for the file.

To empty the file, you could do a > /tmp/log.txt

Same as above, either cron or shell script.
