Is it possible to use indirection for setting variables? This isn't a good method, but your note about controlling variable names within a program is right on. |

What does ${1+“$@”} mean in a shell script, and how does it differ from “$@”? @StephaneChazelas Thanks for the link. I've only been subscribed to austin-group-l for about a year... I found their system difficult to search for relevant historical discussions. |

What does ${1+“$@”} mean in a shell script, and how does it differ from “$@”? @StephaneChazelas Interesting about the eval. I'd think that would likely cause a problem when the Perl comes across it. I would never use it for this purpose. WRT set -u, can't reproduce in mksh (only shell listed there in which it says it hasn't been fixed). WRT checking unset vars, I typically use ! ${var+false} for POSIX, which performs best in most shells especially in the true case. ${var+:} false is another alternative. |

Shell script Variable Structure Thanks for showing the correct methods. First example should use ${#snapshot[@]}, ideally (( ! ${#snapshot[@]} )), though in this specific case testing the 0th element will give the illusion of working anyway. |
