The `zdiff` and `gzexe` scripts use the `type` command to identify whether the `mktemp` tool is available. That command exists in XSI-compliant shells and as an external binary or script in some operating systems, but it is missing in simple POSIX-compliant shells. Because those scripts start with `#!/bin/sh` I believe they should work in POSIX-compliant shells. Replacing the use of `type` with `command -v`, or a more complex construct that uses `type` when it is available and falls back to `command -v` otherwise, would allow the scripts to work as intended in those scenarios, rather than silently failing to find the `mktemp` tool when it is available.
Alternately, if the intent is to only target bash, I would propose the shebang be changed, although that could have downstream consequences of introducing a new dependency on systems that don't otherwise need or use bash. I apologize if this has been discussed previously. I was not able to find it in the mailing list archives, but I am also unfamiliar with the organization of the GNU projects' communication and development channels. I am sending this email without subscribing to the list because that seems to be the suggested approach in the docs; please let me know if there is a better way to address this concern. -- Sparr spa...@gmail.com http://github.com/sparr
