Just seeing the contortions you guys go through to make backticks and tildes work makes me wonder how many months you wasted figuring that bit out. You could have been doing something useful/valuable instead.
I wasted 0.000004 months figuring that out.
You'd have saved that time by learning better scripting skills. Backticks have been deprecated for a long time (ambiguous nesting - use $(blah) instead), and I don't know where you'd NEED to use a tilde (bare "cd" takes you $HOME).
I also wish you people would learn to use blockquote.
Does it really only take 0.000004 months to learn better scripting skills? I guess it might, for all I know. I haven't written a line of code in many, many moons. And notice how I learned how to use blockquote! Another 0.000004 months put to good use!
Variables don't; constants aren't.
