Sure, but bash is written in c and it can call its functions whatever it
likes because they are built into the program. (It will also try to interpret
your file name if it isn't alphanumeric)
The reason why I listed those examples is not to say that you could just
use the special punctuation instead of letters. I'm just pointing you to
what looks like a standard notation for writing those same concepts as
letters, so that you write >= as "ge" instead of "greaterthanorequal" or
"greaterequal" or "greq" or any other long and nonstandard combination.
That's all I mean. Do you understand?
