TBH, it depends... I usually have to double-check the usr/env shebang for bash in the first place.. even then, will google my way through it.

I work mostly in node.js these days, and will have others on windows or mac, and deploys to linux. A node script is usually safer for me, and I'm far more proficient... shell.js, mz and babel-cli makes it easier to do task scripts for automation. ymmv though.

It I had to write a bash script without the benefit of google, I'd totally fail.
