By defining a funct= ion containing the command, any command can be used. It is not the most beautif= ul option but it will work and isolate the file descriptor manipulation. It will not help if you want to set -eo pipefail to make shell "do what I m= ean" but I think shell will not do proper error handling automatically with any option setting anyway. I already committed a small refactoring in support of -o pipefail to sh whi= ch seems good anyway but I'm not entirely sure yet whether to add this feature. --=20 You are receiving this mail because: You are the assignee for the bug.=
