File size setting
There is a file in my Unix Server whose size will be constant.
But every day when the sheduled jobs run in the server, that file gets updated but the size does not change.
Upon doing file filename
It is dispalyed as a binary file.
Can anyone please explain how that file is created.
How is memory alloted for the file at first itself.
The same file after many months of job run will not get updated.
Then a new fie has to be created.
Thanks In Advance
