ShellCheck found a function that goes out of scope before it's ever
invoked. Verify that the function is called. It could be misspelled, or
its invocation could also be unreachable (as in
f() { ..; }; exit; f
).
Note that if the example script did not end in exit
,
this warning would not be emitted. This is because the function could be
invoked by another script that source
s it.
ShellCheck is currently bad at figuring out functions that are
invoked via trap
. In such cases, please ignore the message with a directive.
ShellCheck is a static analysis tool for shell scripts. This page is part of its documentation.
