find is an external command.
I'm aware that find is an external command.
AFAIK, shellcheck checks for arguments to some external commands to warn if they are not posix compliant.
But I could be wrong about this. Either way, it would be a nice addition to warn that the argument given is not portable.
The comment was: "find
is an external command" .. not shellcheck
In what way do you mean not portable ?
I mean portable as in being easily moved from one system to another.
A script that uses "find -printf" will run perfectly fine on most Linux distros, fail if you move it to one that uses posix utilities, and similarly fail if you were to run it on many other Unixes.

Shellcheck does not warn when one is using "find" with the GNU "-fprint" option.
For bugs
shellcheck --version
or "online"): 0.8.0For new checks and feature suggestions
Here's a snippet or screenshot that shows the problem:
Here's what shellcheck currently says:
[nothing]
Here's what I wanted or expected to see:
In POSIX sh, find -printf is undefined
When I run the command above in dash/bash, I get a listing of all files each on their own line as expected When I run it in busybox, I get "find: unrecognized: -printf"
