I typically use find "$HOME/docs", but with a few caveats:

  • In Zsh or Fish, the quotes are unnecessary: find $HOME/docs
  • If I'm using anything potentially destructive: mv "${HOME:?}/bin" ...
  • Of course, if it's followed by a valid identifier character, I'll add braces: "${basename}_$num.txt"
  • I'm pretty inconsistent when globbing: "$HOME"/docs/* or "$HOME/docs/"* are common for me.
  • I don't use "${HOME}" unless I actually need the braces. The reason? I write more Zsh than anything, and the braces are even less necessary in Zsh: $#array[3] actually gets the length of the third element of the array, rather than substituting the number of arguments, then the string 'array[3]'

I always brace my variables.

While I also use ZSH, I write most of my scripts in bash because they more often than not need to run on a CI/CD server.
