  • This is perfect. No external dependencies (no additional processes created), just as requested. One more part to the question, though—the config I want to read is contained in a specific file. I want to softcode that into the script, allowing for overrides. I've clarified this part of the question above. Commented Nov 20, 2015 at 20:44

    ${1:-default} is useful but @wildcard wanted to test if "$1" was readable ([ -r "$1" ]) before overriding the default. Commented Nov 20, 2015 at 21:00

    @cas Thank you. That's what I get for updating based on comments before reading the updated question... After reflection, I commented on the question about a problem when silently reverting to default. Commented Nov 20, 2015 at 21:13

    i was going to change it to that myself until i re-read the question :) silently reverting is probably bad, but the script could warn or exit if "$1" isn't readable. Commented Nov 20, 2015 at 21:22
