- -c 'check this'
- Things that never work: $10 and [ -n $var ]: Fail by default, add --unbreak/--fix-neverworking
- alias → function
- eval is evil: Color blinking red?
- for i in seq → for ((i…))
- for i in … → while read < <(…)
- reduce perilous boilerplate
- make flush an error for easier propagation
- approach agreement with rust-fmt
- errexit → errtrace ?
- Gotcha: Command substitution "$()" trims whitespace
- Useless uses of find
- cp file dir → cp file dir/
- realpath → readlink -f ?
