I avoid bash scripting for anything time-sensitive because the time it takes to fork commands like chmod quickly adds up and, by OS standards, creating new processes is not a lightweight operation on UNIX-like OSes.

Although one minute isn't a long time it *feels* like an eternity when you're sitting there waiting for it to finish. And unfortunately, it had to be run as part of a series of steps - it was step 2 of 3. Dead bang in the middle, slowing me down to a crawl on every iteration. *sniff* Absolutely right, OJ: that one minute wait was the bottleneck to the task I was trying to accomplish.

If it was a blocker, then there's no doubt you took the right approach and looked to optimise it a bit. If it wasn't a blocker, and you can run the script behind the scenes, then it becomes moot. If you fire and forget, then there's no huge deal between the two. Of course, being a bit of a performance nut, I give you kudos for what you did :) But in the "real" world, if it doesn't slow you down by preventing you from doing anything then it's no biggie. When are you writing the ASM version? :) I think a key point to clarify is whether the script was a blocker for you or not.
