I am a mathematics enthusiast, although I have no formal training. What I know is what I've been able to glean from searching Wikipedia.

I enjoy writing computer programs, although I have never been employed as a programmer. I've used two-dozen different programming languages, but my current favourite is Haskell.

I also have an interest in various areas of science.

On top of all that, I'm also a bad musician, a mediocre dancer, and a very bad juggler. :-P

comment Any reason to use or teach `…` substition for new development?
Wait, backticks are deprecated?? Does anybody have a canonical reference explaining why? (Weird syntax characters are very hard to search on.)

comment Inheriting Bash signal traps
How does one "ignore" a signal? You mean trap - SIGINT permanently disables that signal for all child processes?

How odd... I have no idea why it would do that.

comment Inheriting Bash signal traps
Coming back to my original question, your answer appears to basically say "yes, trap is local to one script file". Is that right?

Nope. It's running from a script file, that successively turns on various traps and prints out the result after each one.

I tried grep /proc/$$/status after various combinations of trap. I seem to get SigCgt: 43817efb in all cases. What the heck...?

comment Bash: issuing trap twice
I read that exact paragraph, but it's not immediately clear to me that "the command arg is to be read and executed" implies that any previous command is removed. That appears to be the case, however.
