This seems to have caused occasional weird side-effects on the following line: edo curl https://raw.githubusercontent.com/haskell/ghcup/master/ghcup > "${HOME}"/.ghcup/bin/ghcup ... edo ghcup install It would result in: ~/.ghcup/bin/ghcup: line 1: $'\E[0': command not found ~/.ghcup/bin/ghcup: line 1: 35mcurl: command not found which seems to be because of printf and the piping command. It's not entirely clear to me what happens here, but it seems part of the printf output to stdout where mixed with the next command.
