Redirect produces zero byte file
I my shell script I call a program and redirect the output to a file.
mypgm > myoutput.file
Once in a while, the output file is zero byte.
The programmer of mypgm said the program always produce some output.
Is there any situation where a redirect will create a zero byte file even if the program actually output something. I want to be sure before I go back to challenge the programmer.
