In RHEL5.4, the following entries in the crontab works:
* * * * * set >/tmp/set.output
* * * * * . my_env && cat my_env >/tmp/deleteme
The file my_env is placed under my home directory with mode 644 owned by me. The file /tmp/set.output and /tmp/deleteme are created as expected.
However the same entries and the same setup doesn't work in RHEL6.4. It doesn't create or write to /tmp/deleteme although I have permission to create files and write to them in /tmp.
The man page says `source` will look for my_env from the PATH. On non-posix shell, the home directory is searched as well. So RHEL6.4 is correct. I wonder if this is an intended improvement or is it something else that makes the behaviour different?

I have changed some output to 'hello' for privacy.
