Oozing Race Conditions
Authored by: xr4ti on Dec 16, '08 02:15:10PM
I've used this script half a dozen times, with 100% success. (Over the last 10 years, I've also used similarly constructed scripts, carefully applied, for unix admin purposes. If you know your target application, and test carefully, scripts like this can be reliable.)

The commenter may not have used common sense when concluding that efax could appear and disappear in less than a 1-second cycle. It it does, then your fax failed to be sent

Also, the script doesn't "pull" a copy, it makes a copy, leaving the original intact and unmolested.

And further, the script waits until the efax process is running which means the file being sent is safe to copy.

In my opinion, a wrapper would be a much worse idea. The next OS update could wipe your wrapper out, and you wouldn't know it until after you lost the chance to copy your next fax.
