[Swift-devel] code to test for file existence in swift

[Michael Wilde]

Mike, could you elaborate on the use case for this?

Do you want the swift code to execute a procedure only if a file exists?

Exists on the submit host?

One way is write a tiny shell script that returns 1 or True if the file 
exists and zero otherwise.  You'll need, I think, to use @extractint: 
the return value (from the test) in fact needs to go into a file, then 
extractint can return t/f based on the value of that file:

@extractint(file) will read the specified file, parse an integer from 
the file contents and return that integer.

if, switch or iterate could then be used to act on the 
exists/doesnt-exist condition.

I'm not sure if there's a more elegant way to do this. Depends a bit on 
your actual use case.

- Mike
