Hello James,
nameoffile.stat.isreg is undefined and nameoffile.stat.isreg == false,
evaluates to true when the file does not exists. I just deleted the target
file, ran the playbook and this one copies the src to target. If the
destination exists does not do anything.
I tried with the statement that you suggested:
flag_to_overwrite or nameoffile.stat.isreg is undefined or not
nameoffile.stat.isreg
but also does not matter what value flag_to_overwrite has, if the
destination exists, the src it isn't copied.
The contents of vars/main.yml is:
---
flag_to_overwrite: true
How to use variables defined outside the *when* clause of the stat module?
I tested again placing inside of* when* clause:
flag_to_overwrite == true
but the file is only copied if destination does not exist.
If the destination does not exist placing flag_to_overwrite to false the
playbook does not change anything (leaving only ----- when:
flag_to_overwrite in the stat module invocation), changing
flag_to_overwrite to true does copy the src to dest only one time. (i.e. if
destination exists it is not overwritten even if flag_to_overwrite is set
to true).
Thanks for your suggestions.
Adam
